:SOURce:MARKer Commands
[:SOURce[<n>]]:MARKer:FREQuency
Syntax [:SOURce[<n>]]:MARKer:FREQuency {<frequency>|MINimum|MAXimum}
[:SOURce[<n>]]:MARKer:FREQuency? [MINimum|MAXimum]
Description Set the mark frequency of the specified channel.
Query the mark frequency of the specified channel.
Parameter Name Type Range Default
[<n>] Discrete 1|2 1
<frequency> Real Refer to the “Explanation” 550Hz
Explanation  For step sweep (the sweep points determined by the start frequency, stop
frequency and number of steps are f
1
, f
2
, ……, f
n
, f
n+1
…… ), if the mark
frequency is one of the sweep point values, the sync signal is TTL high level at
the start of the sweep and will change to low level at the mark frequency point. If
the mark frequency is not any of the sweep point values, the sync signal will
change to low level at the sweep point which is closest to the mark frequency.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related
parameters of CH1 by default.
 The range of <frequency> is limited by the “Start Frequency”
( [:SOURce[<n>]]:FREQuency:STARt ) and “Stop Frequency”
( [:SOURce[<n>]]:FREQuency:STOP ). It must be between the start frequency
and stop frequency.
 After the “Mark Frequency” is modified, the signal generator will output the
sweep waveform from the specified “Start Frequency”.
Return Format The query returns the mark frequency in scientific notation with 7 effective digits, for
example, 5.000000E+02 (the mark frequency is 500Hz).
Example :SOUR1:MARK:FREQ 500 /*Set the mark frequency of CH1 to 500Hz*/
:SOUR1:MARK:FREQ? /*Query the mark frequency of CH1 and the query
returns 5.000000E+02*/
