Gain, Atten & preamp: Auto – request

Hi,

When using the auto combo box option for one or more of the amplitude controls, it would have been nice to see what actual setting is chosen by the SW. This could either have been shown in a parenthesis next to the “Auto…” inside the combo box or on the display window.

Also, when pointing the mouse over the respective combo box, a “mouse over” text field could show for detailed explanation of why that particular gain setting etc has been chosen due to other settings etc.

Hi HC,

You may already know this from our manuals, but the gain and attenuation are optimized based on the reference level. When gain and attenuation are set to automatic, we expect the user to set the reference level just above the expected input signal if the user needs the best dynamic range and sensitivity. For all of our devices, the range in which are devices are optimized is typically between +10 to -50 dBm reference level. This also changes based on frequency and temperature of the device.

Showing the gain and attenuation chosen is a good idea, but can be tricky as when the gain/atten settings are automatic we also optimize gain atten by frequency band as the device sweeps, so in some configurations there is not a signal gain/atten value used.

Regards,
A.J.
