(2) Signal generator + analog transmitter measurement: Analog TX
Meas with SG screen
On the Analog TX Meas with SG screen, output an RF signal from the
MT8801B and measure the RF signal from the DUT.
AF Osc.2 signal can also be output to the AF output terminal as required.
Switch to the Analog TX Meas with SG screen according to the following steps:
Step Key operation Description
