Reviews of our spectrum analyzers

Love not having to pay extra for the full capability of the software. No need to pay extra to demodulate or work with the different protocols.

Hell yeah! Just bought one of these bad boys and it TEARS through the GHz like an ABSOLUTE UNIT!

Meets or exceeds the specifications. Software application is excellent.

My company files for STA (temporary) FCC licensing in the US all the time. We purchased this to unit to help with frequency selection. Since the software tell me the actual 12.5 kHz UHF frequency it is almost useless for my application. Seems like it is a coding issue, but I was told to look at 3rd party software that cost thousands.

We bought 2 of these and for a product with this pricing and performance, I would love to rate above 5 stars if that's possible. Thank you for having such a great product!

It is a shame it does not go down to 2 MHZ, any chance? I also need to cover the lower VHF bands 30-100, VHF FM starts at 88 MHz!

I am sure it could have been a wonderful device. The USB software connected just fine on three different computers with three different operating systems, but it would not control the TG44. It was a hardware problem. Support was from software people who were arrogant and condescending. The unit would only generate 10 mHz. Support would not send a replacement unit, but insisted that I send it in for repair. Knowing the evaluation period was ending, I returned the unit and went another direction as I feared I would be stuck with this brick. What a waste of my time!

I bought a USB-SA44B for its small size so I could carry my own analyzer during the installation of satellite downlink equipment. I was particularly pleased with the ease of use of the Spike software. The only thing I would like to see with the ability to start Spike with one of the presets. A great product indeed!

Do you have some distributor in Ecuador? I will need a demo of Vector Signal Generator.

This unit is perfect for my lab needs and this is my initial review. I aim to follow up once I have had enough time on it. The Pros ------------- Value for money 5 stars Support is excellent from AJ and team Spectrum Analysis, accurate and quick but needs to have a low span as expected for the most accurate frequency match. Marker function is easy to use and deltas are quick to do Digital Demodulation works fine for my needs, lots of options that can be confusing so take your time setting it up EVM measurement is fairly accurate, still getting used to it though The real-time option is very useful but I am still getting used to it as have always in the past used non-real-time analysers This unit replaced an older Agilent I had and I am very happy with it. Cons -------- Getting used to a PC based USB instrument takes time The USB power option unless you have an external compatible hub was problematic for me using a laptop. I had endless disconnection issues until I found a compatible powered hub. I would prefer the unit to come with a separate supply and not take power from USB or a compatibel hub that is powered be supplied with the unit. Thanks for a product that the price is unbeatable. Together with my VSG I can pretty much do everything I need.

We own 4 products from SH: 4 GHz spectrum analyzer in combination with a tracking generator, and the same for the 12 GHz version. We use them extensively for scalar network analysis when building our customized microwave instruments for spectroscopy (in physics). The products have a great price to performance ratio. We had complications when installing the drivers and running the instruments, having a strong hardware was the key. Besides the pros, we encountered a very annoying problem: we often (3-5 times per day) screw-unscrew our units and cables onto the devices. After a few months ,the female SMA connectors broke and started to loose the inner pins. Given that we have other similar devices which have endured the same treatment over several years, we reckon that Signalhound was saving on the quality/cost of the connectors. Given that we were over the guarantee, we attempted to change the connectors ourselves, which has lead to deteriorated performance at 10 GHz. At present, we are using the devices while having a short SMA female-male adapter attached to it permanently, to avoid damage to the connectors on the devices.

I have owned the Signal Hound Spectrum Analyzer/Tracking generator for the past several years. With the SPIKE software, I would give it an excellent rating. I have also used the comparably price Rigol and much prefer the Signal Hound.

A welcome addition to my lab. I have used this analyzer many times since I purchased it, examining signals from low audio to high UHF, and while it does not have the flexibility of an HP, it is a darn good analyzer for many of my purposes. Having made a sleep-deprived cable mix-up one late evening, I must warn users to take the maximum input level VERY SERIOUSLY! That was an expensive mistake!

This is a great little tool very useful. There are some minor things I would like to see changed. Most is software related other is BNC connector instead of SMA connectors.

this is good product its economy price

would be nice to have a kit with 2 dc block pads , as the tg44A already comes with a 20dB pad and just one dc block pad will not solve the problem when measuring amplifiers.

Very pleased with both the BB60A and TG44A. Studied similar units seriously for about a month before deciding on Signal Hound. Rapid response to my questions from the Signal Hound team, no upgrade charges for the wonderful spike software, Facebook page and forum makes me feel like part of the Signal Hound family.

This instrument has performed exceedingly well in our application. The aspect that is the most striking to me is how well implemented and documented the API is. Getting the device up-and-running and taking data was very easy.

Great little device. I bought it with the tracking generator to tune filters. I use it to take occupied band width measurements for broadcast and checking for harmonic emissions as well as for my amateur radio use.

In our work we develop prototypes of RF systems. We have struggled in the past using handheld and bench top analyzers as tag along devices for RF systems we were testing or demonstrating. We found the Signalhound to be easy to work with, rapidly programmable and to be of a size that we can incorporate into our prototypes so that external equipment is not required. We are also pleased to find added features and performance from this device that we were unable to find from other much more expensive sources.

The SA44B is a great device and specifically quite good at providing the dynamic range I need for my narrow specifications. I build and test Faraday cages for MRI applications and the test is usually a half hour attaboy after a week of work. The Signal Hound unit is so light and easy to set up that I have quit moaning the demise of my HP. So far I have not had the "opportunity" to troubleshoot with the SA44B.

once past the initial questions, up and running for a 3 hour flight to test for interfering signals in the cabin. the recording function works well, overall a really good tool.

The unit and software are great. It really allows me to verify the operation of the BTLE and other 2.4 GHZ digital RF devices we design.

Excellent product. I am primarily using it in my persuit of Amateur Radio. It has proven s valuable tool allowing me to improve my RF noise environment around my home as well as in monitoring the performance of my equipment. Along with the tracking generator and optional directional Coupler it has proven valuable in optimizing the performance of my antennae.

Great device. This spectrum analyzer gave me all the functionality I needed to complete the design of a new RF product. Everyone asks me about the device and how they can get one.

This spectrum analyzer has saved my life so many times, I can't clearly recall each one. From lab use at my atomic time scale and precision frequency standards lab, to Grand Prix Formula 1 frequency coordination and monitoring work. Amateur radio aside (where I found the most useful tool of all to enjoy the hobby) the SA44B has proven to be an intelligently designed spectrum analyzer that allowed me to reach my RF measuring goals every time. Thank you Bruce and your team for such a nice experience both with your products and while talking to you and Cory over the phone. By the way I am waiting for my SA124B to be delivered to me tomorrow. I feel like an impatient child a day before receiving his birthday present. Now, what are the rest of the instruments that my Signal Hound collection lacks? Consider yourselves warned that I am surely coming back for more. Cheers! Edgardo Molina. XE1XUS.

I've owned one of these for several years, and I know that quite a few folks, after seeing mine, also purchased one. This is an incredible device for the $. When I first received mine, I checked it against my Agilent SA and the Signal Hound was within a 1/2 dB. I use mine in the DAS (Distributed Antenna System) world, and the SA44B, when combined with the matching tracking generator gives me all I need to setup a DAS. I added a broad band amplifier from Mini-Circuits, so I can get levels higher than +15 dBm (from the tracking generator). With the software utility that lets the Tracking Generator work as a stand alone signal generator, the tracking generator (along with the Mini-Circuits amplifier) lets me perform simulated coverage studies (from a single antenna location). I will admit (and caution folks) that this can't do everything that some higher priced units do, but the SA44B has enough capabilities, that you don't often need the more expensive boxes.

I was faced with a huge overweight bill if I was to take our R&S Spectrum Analyser with me to Papua New Guinea (16Kg being the limit). The overweight bill was going to be about the same price as the SA44B so it was a no brainer to buy one and pack it in with my carry on laptop computer. The results were fantastic and far exceeded my expectations when trying to track down spurious emissions at a remote site near Wewak, PNG. Job done and now the SA44B remains in my computer bag as part of my travelling kit. Highly recommended for any RF Engineers.
