Bypass Gain Adjust Calibration
Description
This calibration adjusts the gain adjust DAC on the A13 Output 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.
Required Test Equipment
• Agilent E4418B E-Series power meter
• Agilent E9304A E-Series power sensor
