REMOTE OPERATION
5-24
Sweep operation
SWEEP
[not used alone]
:CFRQ
Optional command (may be omitted)
:START
Set Start Frequency
:STOP
Set Stop Frequency
:INC
Set Carrier Frequency sweep step size
Data type :
Decimal Numeric Program Data
Allowed suffices :
Any one of: GHZ, MHZ, KHZ or HZ
Default suffix :
HZ
:TIME
Select time per sweep step
Data type :
Decimal Numeric Program Data
Allowed suffices :
MS, S
Default suffix :
MS
Example:
SWEEP:CFRQ:START 100KHZ;STOP 500KHZ;INC
100HZ;TIME 60MS
SWEEP:CFRQ?
Prepares message containing information on Carrier Frequency Sweep
settings in the following format:
:SWEEP:CFRQ:START <nr2>;STOP <nr2>;INC <nr2>;TIME <nr2>
Example:
:SWEEP:CFRQ:START 1230000.0;STOP 1330000.0;INC
100.0;TIME 20.0
Sweep mode
Note that for triggering the order of priority is as follows:
FSK logic input
Memory recall
Sweep trigger
Therefore ensure that FSK is not enabled, otherwise selecting sweep triggering will have no effect.
