MEAS TIME
The
MEAS TIME
softkey activates the entry field for the measurement time.
This softkey is also available in the RECEIVER / MEAS menu.
Remote command:
SWE:TIME 100ms
Effect of measurement time with different weighting modes:
• MIN/MAX PEAK measurement:
With peak weighting selected, the maximum or minimum level during the selected
measurement time is displayed. The peak detector is reset at the beginning of
each measurement. At the end of the measurement time the maximum or
minimum level occurred during the measurement time is displayed. Since the
peak detector of R&S ESU is a digital detector, discharging is irrelevant even with
long measurement times.
Unmodulated signals can be measured with the shortest possible measurement
time. When pulses are measured, the selected measurement time must be long
enough for at least one pulse to occur during the measurement time.
• Average measurement:
With average detection selected, the video voltage (envelope of IF signal) is
averaged during the measurement time. Averaging is digital, i.e. the digitized
values of the video voltage are summed up and divided by the number of samples
at the end of the measurement time. This corresponds to a filtering with a
rectangular window in the time domain and a filtering with sin x/x characteristic in
the frequency domain. With unmodulated signals the shortest possible
measurement time can be selected. With modulated signals the measurement
time is determined by the lowest modulation frequency to be averaged. With pulse
signals, the selected measurement time should be long enough for sufficient
number of pulses (>10) to occur in the measurement window for averaging.
