SOURce:MARKer SME
1038.6002.02 3.78 E-13
3.6.11.10 SOURce:MARKer Subsystem
This subsystem contains the commands to check the marker generation with sweeps. The SME has
three markers each for frequency and level sweeps which are differentiated by a numeric suffix after
MARKer. The settings for frequency sweep and level sweep marker are independent of each other.

[:SOURce]:MARKer1|2|3[:FSWeep]
The commands for the markers with frequency sweep are under this node. Keyword :FSWeep
can be omitted, then the command conforms to SCPI regulations.
[:SOURce]:MARKer1|2|3[:FSWeep]:AMPLitude ON | OFF
The command specifies whether the marker influences the signal level.
ON The output level is reduced by a constant value when the marker frequency is
executed.
OFF The output level remains unchanged. *RST value is OFF
Example: :SOUR:MARK1:FSW:AMP ON
[:SOURce]:MARKer1|2|3[:FSWeep]:AOFF
Command (All markers off
) switches off all frequency markers. This command triggers an event,
thus it has no *RST value and no query form.
Example: :SOUR:MARK:FSW:AOFF
[:SOURce]:MARKer1|2|3[:FSWeep]:FREQuency 5 kHz to 1.5 GHz (SME03E/03/06: 5 kHz to F/3/6
GHz)
The command sets the marker selected by the numeric suffix with MARKer to the frequency
indicated.
In this command, the OFFSet value of the subsystem (menu) FREQuency is considered as with
input value MARKER in the SWEEP-FREQ menu. Thus the specified range indicated is only valid
for SOURce:FREQuency:OFFSet = 0. The specified range with other OFFSet values can be
calculated according to the following formula (cf. Chapter 2, Section "Frequency Offset", as well):
5 kHz - OFFSet to 1.5 GHz - OFFSet *RST value for MARK1: 100 MHz
MARK2: 200 MHz
Example: :SOUR:MARK1:FSW:FREQ 30MHz MARK3: 300 MHz
