R&S ESU Instrument Functions
Basic Settings
The preset value is at -200 dBm. The field is displayed if the value RELATIVE is
entered in the field Y-SCALING.
Remote command:
CALC:LIM3:UPP:THR -30 dBm
or
CALC:LIM3:LOW:THR -30 dBm
Comment - Enter comments
Comments are arbitrary, however, they must be less than 41 characters long.
Remote command:
CALC:LIM3:COMM "Upper limit"
VALUES The VALUES softkey activates the entry of the data points in the table columns
Time / Frequency and Limit/dB . Which table columns appear depends upon the
Domain selection in the table heading.
The desired frequency/time data points are entered in ascending order (two
repeated frequencies/time values are permitted).
Remote command:
CALC:LIM3:CONT:DATA 1MHz,3MHz,30MHz
CALC:LIM3:UPP:DATA -10,0,0
CALC:LIM3:LOW:DATA -30,-40,-40
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
