MARKer Subsystem

The MARKer subsystem configures the point within an arbitrary waveform, sweep, or burst at which the front panel Sync signal goes low.

Commands and Queries

If and only if the SYNC:MODE is set to MARKer, each of these commands causes sync/marker to transition to high at start of burst, sweep, or arbitrary waveform. OUTPut:SYNC:POLarity may reverse this.

[SOURce[1|2]:]MARKer:CYCle {<cycle_num>|MINimum|MAXimum|DEFault}
[SOURce[1|2]:]MARKer:CYCLe? [{MINimum|MAXimum}]

Sets the marker cycle number at which the front panel Sync signal goes low in a burst mode operation. OUTPut:SYNC:POLarity may reverse this.

Parameter Typical Return
Whole number from 2 to number of cycles in the burst plus one (NCYCles+1), default 2 +2.000000000000000E+03
Set the marker cycle to 2000:
MARK:CYCL 2000

[SOURce[1|2]:]MARKer:FREQuency {<frequency>|MINimum|MAXimum|DEFault}
[SOURce[1|2]:]MARKer:FREQuency? [{MINimum|MAXimum}]

Sets the marker frequency at which the front panel Sync signal goes low during a sweep. OUTPut:SYNC:POLarity may reverse this.

Parameter Typical Return
Any frequency between start and stop frequency, default 500 Hz

+2.000000000000000E+03

Set marker frequency to 2 kHz:
MARK:FREQ 2000

[SOURce[1|2]:]MARKer:POINt {<sample_number>|MINimum|MAXimum}
[SOURce[1|2]:]MARKer:POINt? [{MINimum|MAXimum}]

Sets the sample number at which the front panel Sync signal goes low within the active arbitrary waveform. OUTPut:SYNC:POLarity may reverse this.

Parameter Typical Return
Whole number from 4 to number of samples in waveform, minus 3; default is midpoint of arbitrary waveform

+1.000000000000000E+01

Set marker point to 10th sample in waveform:
MARK:POIN 10
