.
Channel number
Parameters:
<Boolean> ON | OFF - enables or disables intermodulation spectrum mea-

*RST; FREQ:IMOD:LTON PORT,1; UTON GEN, 1
Reset the instrument to create the default channel no. 1. Select
port 1 as a source port for the lower tone, a (previously config-
ured) external generator no. 1 as a source port for the upper
tone.
FREQ:STAR 1GHZ; STOP 2GHz
Define a suitable sweep range to ensure that the analyzer can
measure all intermodulation products.
SENS1:FREQ:IMOD:SPEC ON
Enable the intermodulation spectrum measurement for channel
no. 1.
CALC1:PAR:CAT?
Query the traces in channel no. 1. The response is
'Trc1,B2D1SAM'.
