SPGU Pulse Setup Parameters
The following setup is required to apply the SPGU pulse. See “SPGU Control” on
page 5-57 for the GUI.
1. Set the following for the SPGU channel on the Channel Setup tab screen.
• Set the V Name of the SPGU.
• Set the Mode to VPULSE. This sets the PG mode. Do not set to ALWG.
2. On the SPGU Pulse Setup window, specify the following parameters for the
SPGU. See Figure 7-
17 for the pulse setup parameters.
Period Pulse period. 20 ns to 10 s, 10 ns resolution.
Operation FREE RUN, PULSE COUNT, or DURATION.
In the FREE RUN mode, the SPGU continues the pulse
o
utput u
ntil the measurement is completed or stopped. Not
available for the SPGU Control classic test.
For the PULSE COUNT mode, specify the number of
pulses, within
the range of 1 to 1000000. The SPGU will
output the specified number of pulses.
For the DURATION mode, specify the total time to output,
within the range o
f 1 μs to 31556926 s (1 year). The SPGU
will continue
to output until the specified time elapses.
Type 2-Level Pulse or 3-Level Pulse. If you choose 3-Level
Pulse, the Addition
al Pulse fields become effective.
Base, Peak Pulse base and peak voltage. 0 to ± 40 V (open load), ± 20
V (50 Ω lo
ad), 1 mV resolution.
Delay Delay time. 0 s to Period-20 ns
, 2.5 ns resolution.
Resolution will be set at 10 ns if the pulse transition time is
> 8 μs.
Width Pulse width. 10 ns to Period-10 ns
, 2.5 ns resolution.
Resolution will be set at 10 ns if the pulse transition time is
> 8 μs.
Leading,
Trailing Pulse transiti
on time. 8 ns to 400 ms, 2 ns resolution.
Resolutio
n will be set at 8 ns if the pulse transition time is >
8 μs.
