MARKer:FREQuency {<frequency>|MINimum|MAXimum}
MARKer:FREQuency? [MINimum|MAXimum]
Set the marker frequency. This is the frequency at which the signal on the
front-panel Sync connector goes to a logic low during the sweep. The Sync signal
always goes from low to high at the beginning of the sweep. Select from 1 mHz to
10 MHz (limited to 100 kHz for a ramp waveform). The default is 500 Hz. MIN =
the start or stop frequency (whichever is lower). MAX = the start frequency or stop
frequency (whichever is higher). The :FREQ? query returns the marker frequency
in hertz.
– When sweep is enabled, the marker frequency must be between the specified
start frequency and stop frequency. If you attempt to set the marker frequency
to a frequency not in this range, the function generator will automatically
set
the marker frequency equal to the start frequency or stop frequency
(whichever
is closer). From the remote interface, a “Settings conflict” error will be
generated and the marker frequency will be adjusted as described.
MARKer {OFF|ON}
MARKer?
Disable or enable the frequency marker. When the frequency marker is disabled,
the signal output from the Sync connector is the normal Sync signal for the carrier
waveform (see “Sync Output Signal” on page 81). The default is OFF. The MARK?
query returns “0” (OFF) or “1” (ON)
.
–The OUTP:SYNC command is overridden by the setting of the MARK command.
Therefore, when the marker frequency is enabled (and the sweep mode is also
enabled), the OUTP:SYNC command is ignored.
