NUMBER OF
SWEEPS
The NUMBER OF SWEEPS softkey activates the entry of the number of sweeps for
maximum or average value calculation.
The valid range values is 0 to 32767.
Depending on the specified number of sweeps, averaging is carried out according to
the following rules:
Remote command: SWE:COUN <value>
Example
The mean power of a GSM burst with 0 dBm nominal power at 800 MHz is to be
measured.
SINGLE SWEEP mode The R&S ESU performs sweeps until the
selected number of sweeps is reached and
stops then.
CONTINUOUS SWEEP mode Averaging is carried out until the selected
number of sweeps is reached. After that,
averaging is performed in continuous mode
and is then continued as running averaging.
Calculation of the maximum peak (MAX
HOLD) is performed continuously irrespective
of the selected number of sweeps.
NUMBER OF SWEEPS = 0 Continuous averaging is carried out over 10
measured values.
NUMBER OF SWEEPS = 1 No averaging, maxhold or minhold is carried
out.
NUMBER OF SWEEPS > 1 Averaging is carried out over the set number of
measured values.
This setting is equivalent to the setting of the sweep count in the TRACE menu.
[PRESET] Set the R&S ESU to the default setting.
[FREQ: CENTER: 800 MHz] Set the center frequency to 800 MHz.
[SPAN: ZERO SPAN] Select time domain display (span = 0 Hz).
[AMPT: 0 dBm] Set the reference level to 0 dBm.
[BW: RES BW MANUAL: 30
kHz]
Set the resolution bandwidth to 30 kHz in line
with the requirements of the GSM standard.
[SWEEP: SWEEPTIME
MANUAL 600 µs]
Set the sweep time to 600 µs.
[TRIG: VIDEO: 50%] Use the video signal as trigger source.
[MEAS] Call the menu for the measurement functions.
