R&S FSP Instrument Functions
Basic Settings
INSERT VALUE The INSERT VALUE softkey creates an empty line above the current cursor position
where a new data point may be entered. However, during the entry of new values, it
is necessary to observe an ascending order for frequency/time.
Remote command:
--
DELETE VALUE The DELETE VALUE softkey erases the data point (complete line) at the cursor
position. All succeeding data points are shifted down accordingly.
Remote command:
--
SHIFT X LIMIT
LINE
The SHIFT X LIMIT LINE softkey calls an entry window where the complete limit line
may be shifted parallel in the horizontal direction.
The shift takes place according to the horizontal scale:
– in the frequency domain in Hz, kHz, MHz or GHz
– in the time domain in ns, µs, ms or s
In this manner, a new limit line can be easily generated based upon an existing limit
line which has been shifted horizontally and stored (
SAVE LIMIT LINE softkey)
under a new name ( NAME softkey).
Remote command:
CALC:LIM3:CONT:SHIF 50KHz
SHIFT Y LIMIT
LINE
The SHIFT Y LIMIT LINE softkey calls an entry window where the complete limit line
may be shifted parallel in the vertical direction.
The shift takes place according to the vertical scale:
– for logarithmic units, relative, in dB
– for linear units, as a factor
In this manner, a new limit line can be easily generated based upon an existing limit
line which has been shifted vertically and stored (
SAVE LIMIT LINE softkey) under a
new name ( NAME softkey).
Remote command:
CALC:LIM3:CONT:UPP:SHIF 20dB
CALC:LIM3:CONT:LOW:SHIF 20dB
SAVE LIMIT
LINE
The SAVE LIMIT LINE softkey stores the currently edited limit line. The name can be
entered in an input window (max. 8 characters)
Remote command:
--
4.6.1.3 Display Lines
Display lines help to evaluate a trace – as do markers. The function of a display line
is comparable to that of a ruler that can be shifted on the trace in order to mark
absolute values.
The R&S FSP provides two different types of display lines:
• two horizontal level lines for marking levels – Display Line 1/2,
• two vertical frequency or time lines for marking frequencies or points in time –
Frequency/Time Line 1/2.
