Programming a Tx Spurious Emissions Measurement
Programming a Tx Spurious Emissions Measurement
This section provides an example of how to make transmitter spurious emissions measurements via GPIB.
The following program example assumes that the mobile station’s antenna output is connected to the RF
IN/OUT connector, and the mobile station has found service.
The basic procedure to measure spurious emissions remotely is:
1. Turn on the mobile station and perform a registration (wait for power-on or send
“CALL:REGister[:IMMediate]” ).
2. Turn off timer-based registrations (see “CALL:REGister:TIMer:STATe” ).
3. Set up nominal power, initial power, step size, number of steps, and the maximum number of access probes
for responses (see “CALL[:CELL]:APARameter” on page 268).
4. Set the trigger arm state to single (see “SETup:CTXSpurious:CONTinuous” ).
5. Perform a page or mobile station originated call.
6. Initiate the spurious emissions measurement using the “INITiate:<measurement mnemonic>[:ON]” on
page 478. The <measurement mnemonic> for the cdma2000 transmitter spurious emissions measurement
is CTXS.
7. Use the “FETCh:CTXSpurious[:ALL]?” command to obtain the measurement results.
