8-14-10. SOURce[1|2]:MARKer:FREQuency
Set
Query
Description Sets or queries the marker frequency. The default marker
frequency is 550 Hz. The marker frequency is used to output
a trigger out signal from the trigger terminal on the rear panel.
Note The marker frequency must be between the start and stop
frequencies. If the marker frequency is set to a value that is
out of the range, the marker frequency will be set to the center
frequency and a “settings conflict” error will be generated.
Syntax SOURce[1|2]:MARKer:FREQuency
{<frequency>|MINimum|MAXimum}
Parameter <frequency> 1μHz ~ 25 MHz
1 μHz ~ 1 MHz (Ramp)
Example SOUR1:MARK:FREQ +1.0000E+03
Sets the marker frequency to 1 kHz.
Query Syntax SOURce[1|2]:MARKer:FREQuency? [MINimum|
MAXimum]
Return Parameter <NR3> Returns the marker frequency in Hz.
Example SOUR1:MARK:FREQ? MAX
+1.0000E+03
Returns the marker frequency (1 kHz).

start of each sweep and goes low at the
marker frequency.
MARKer OFF The SYNC terminal outputs a square wave
with a 50% duty cycle at the start of each
sweep.
