Recently, i had purchased a TG44A and SA44B. As stated in the manual, the combination of both TG44A and SA44B will be functioned as a scalar network analyzer. I will like to know that is it possible to treat TG44A as a signal generator without combine SA44B with a BNC cable? I will like to fix an antenna at TG44A as a transmitter and an antenna at SA44B as a receiver. Is it possible? Thanks. I will appreciate that if someone reply my question. URGENT.

The BNC cable is used to sync the 2 units together for scalar mode. The TG will function without necessarily being tethered to the SA. In CW (non sweep) mode the TG will produce an RF signal on whatever frequency you tell it to go to.
Simple experiment: Why don’t you try it.
Also note that the TG44 is much happier loading into a 50 ohm load so the admonition of using a 20 db attenuator in series with an unknown load will help flatten out the power level while adjusting the antenna.

The TG44 can be used as a standalone generator. There is an application called TGStandalone in the Spike application installation directory which allows you to set the frequency and amplitude of the generator.

I appreciated for KBONE and Andrew’s reply. Unfortunately, i got another question,i might need to know if there is any calibration need to be done if my TG44 does not tethered to the SA?

The TG44 does not need the SA to generate calibrated outputs.
