Frequency Domain Point-in-Pulse Measurements

This chapter contains measurement calibration and measurement procedures to display the
pulsed-RF S-parameters versus frequency.

Measurement Calibration for Point-in-Pulse

Measurement calibration for point-in-pulse is accomplished in exactly the same way as for the
standard HP 8510.
1. Press NNNNNNNNNNNNNNNNNNNNNNNNNNNNN

displayed, select the wideband detector by pressing

DETECTOR: WIDE BW
2. Select the maximum number of points required for the measurement, then perform the
appropriate measurement calibration.
Note for internal triggering, when you press the key to measure the calibration standard, the
HP 8510 pulse output signal is set to the active state (RF always On) during measurement of
the standard. This assures that the calibration is made with respect to the On portion of the
pulse independent of the trigger delay.
Note for external triggering, you control the pulse width and duty cycle during calibration and
measurement. You must set the trigger delay to make the measurement at the correct time
during the pulse for calibration, then not change it during the measurement.

Set Pulse Polarity

After instrument preset, the pulse polarity is set to High for the On period of the pulse
appearing at the HP 8510 rear panel PULSE OUTPUT connector. Use the following
procedure to set the pulse polarity.
