6.5.4.4 CALCulate:MARKer:FUNCtion:STRack Subsystem
The CALCulate:MARKer:FUNCtion:STRack subsystem defines the settings of the signal track.
CALCulate<1|2>:MARKer<1...4>:FUNCtion:STRack[:STATe] ON | OFF
This command switches the signal-track function on or off for the selected measurement window. The
function is independent of the selected marker, i.e. the numeric suffix <1...4> of MARKer is irrelevant.
With signal track activated, the maximum signal is determined after each frequency sweep and the
center frequency is set to the frequency of this signal. Thus with drifting signals the center frequency
follows the signal.
Example:
"CALC:MARK:FUNC:STR ON"
'Switches on the signal track function for screen A.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A-F
CALCulate<1|2>:MARKer<1...4>:FUNCtion:STRack:BANDwidth|BWIDth 10Hz to MAX(SPAN)
These commands have the same function. For the selected measurement window they define the
bandwidth around the center frequency within which the largest signal is searched. The function is
independent of the selected marker, i.e. the numeric suffix <1...4> of MARKer is irrelevant. It is only
available in the frequency domain (span > 0).
The entry of the search bandwidth is only possible if the Signal Track function is
switched on (CALC:MARK:FUNC:STR ON).
Example:
"CALC:MARK:FUNC:STR:BAND 1MHZ"
'Sets the search bandwidth for screen A to 1 MHz.
"CALC:MARK:FUNC:STR:BWID 1MHZ"
'Alternative command for the same function.
Characteristics: *RST value: -- (= span/10 on activating the function)
SCPI: device-specific
Mode: A-F
CALCulate<1|2>:MARKer<1...4>:FUNCtion:STRack:THReshold -330dBm to +30dBm
This command defines the threshold above which the largest signal is searched for in the selected
measurement window. The function is independent of the selected marker, i.e. the numeric suffix
<1...4> of MARKer is irrelevant. It is only available in the frequency domain (span > 0).
The response unit depends on the settings defined with CALC:UNIT.
The entry of the search bandwidth is only possible if the Signal Track function is
switched on (CALC:MARK:FUNC:STR ON).
Example:
"CALC:MARK:FUNC:STR:THR -50DBM"
'Sets the threshold for signal tracking in screen A to -50 dBm.
