Hints for Taking Measurements.
H
It takes longer to detect pulses when the analysis length in the Timing menu
is set to a larger value.
H
The results are not displayed in the Channel Power, OBW, or EBW
measurement.
The number of data samples in Pulse-On must be 20 to 16,384 for FFT
calculation. Change the span to display the results.
H
The results are not displayed in the Pulse Repetition Interval or the
Duty Cycle measurement.
The observed pulse and the next one must be contiguous. If either pulse is
not recognized due to noise and so on, the measurement results are not
shown.
Error messages (displayed on the bottom of the screen)
H
Message: Filter bandwidth is too wide or Channel bandwidth is too wide.
Indicates that you set Filter Bandwidth or Channel Bandwidth inappropriate-
ly in the Meas Setup menu (refer to page 3--100).
In this case, change the setting of Filter Bandwidth or Channel Bandwidth
until the message disappears.
H
Message: Too long pulse.
Indicates that the number of data samples of a pulse width exceeds about
260,000.
In this case, change the span.
H
Message: Too long repetition interval.
Indicates that the number of data samples of a pulse repetition interval
exceeds about 260,000.
