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

l MARKer:CYCle - cycle of a burst at which Sync signal goes low

l MARKer:FREQuency - frequency at which Sync signal goes low

l MARKer:POINt - point in an arbitrary waveform at which Sync signal goes low

Each of these commands causes sync/marker to transition to high at start of burst, sweep, or arbitrary waveform (OUT-

Put:SYNC:POLarity may reverse this.).

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

[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. OUT-

Put: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

l This is valid only if burst is enabled and OUTP:SYNC:MODE is MARKer.

l With burst enabled, marker cycle must be less than number of cycles in burst plus one. Attempting to set the

marker cycle outside this range will set marker cycle equal to middle of burst. From the remote interface, a "Set-

tings conflict" error will also be generated.

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

[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

l This is valid only if burst is enabled and OUTP:SYNC:MODE is MARKer.
