completion.
To PCS Interface> SYST:PRES; *OPC? ( page 113 )
NOTE: The SYST:PRES command string will reset the PCS Interface but will maintain the current
temperature compensation. Do not use the *RST command during this initialization since
it will reset the temperature compensation. Compensations will be done at the first time
requested following the
*RST
command.
Set Up the UUT
ports
The internal signal path switches of the PCS Interface can be controlled to route
the Test Set’s connections to or from the UUT.
1. Use the following command string for RX testing at the PCS Interface’s RF OUT only
port and for TX testing at the PCS Interface’s RF IN/OUT port.
To the PCS Interface> RF:PATH 1 ( page 107 )
2. Use the following command string for both RX and TX testing at the PCS Interface’s
RF IN/OUT port.
To the PCS Interface> RF:PATH 2 ( page 107 )
NOTE: When the RF:PATH command is executed, the TX and RX attenuators are automatically
set to their maximum values of 40 dB and 70 dB, respectively.
