Sweep Measurements
To Set up PGU Output
1. Define PGU to be VPULSE and CONST as described in “To Define
Measurement Units” on page 4-12.
2. Press Meas key in the PAGE CONTROL key group.
3. Select PGU SETUP primary softkey.
4. In the PERIOD field of PGU1, enter the pulse period value.
5. In the WIDTH field of desired PGU column, enter the pulse width value.
6. In the DELAY TIME field of desired PGU column, enter delay time value.
7. In the PEAK VALUE field of desired PGU column, enter pulse peak value.
8. In the BASE VALUE field of desired PGU column, enter pulse base value.
9. In the LEADING TIME field of desired PGU column, enter the leading-edge
transition time.
10. In the TRAILING TIME field of desired PGU column, enter the trailing-edge
transition time.
11. In the IMPEDANCE field of desired PGU column, select:
• LOW secondary softkey for approximately zero ohm output impedance.
• 50 ohm secondary softkey for 50 ohm output impedance.
12. In the PULSE COUNT field, do one of the following:
• Select FREE RUN secondary softkey to force the pulse continuously.
• Or enter the number of pulses to output (for sampling measurement only).
For the pulse period and pulse count values, the values you set for PGU1 are also
used for PGU2. The following figure shows the relation between pulse waveform
and setup parameters.
