Low Noise Floor Gain Adjust
(ESG-AP and ESG-DP only)
Description
This adjustment calibrates the gain adjust DAC on the output module for low noise floor
(LNF) mode. The instrument is set up with attenuation applied by way of the burst
modulator. This ensures that the RF chain is not in compression. The gain adjust DAC is
then set for a specific RF output power, as measured with a power meter.
