Section 1: Getting Started Model 4200-SCS User’s Manual
High-endurance output relay (HEOR): Each output channel of a pulse card has a high-speed,
solid-state output relay. When this relay is closed, the
waveform segment is output. When opened, the channel
output is electrically isolated (floating) from the DUT. In
Figure 1-22, the output relay is opened during segment
seven. This puts the output in a floating condition. The
minimum time for a segment with a HEOR transition
(open-to-close or close-to-open) is 100 µs for the
4205-PG2 or 25 µs for the 4220-PGU and 4225-PMU.
NOTE If the firmware for the 4200-PG2 has been upgraded to KITE V6.2, it can be used to
configure and output Segment ARB
®
waveforms (see Firmware upgrade for the
4200-PG2 earlier in this section). However, the 4200-PG2 does not have output
relays (HEOR). Therefore, relay control will be ignored.
seg_arb_define:
This function is used to define a Segment ARB waveform. This function includes parameters to
specify the number of segments (nSegments), and arrays for start (startvals), stop
(stopvals), and time values (timevals). It also includes arrays for trigger levels
(triggervals) and output relay states (outputRelayVals). For more information, refer to the
Reference Manual, seg_arb_define, page 8-175.
seg_arb_file:
This function is used to load a Segment ARB waveform into a pulse card. For more information,
refer to the Reference Manual, seg_arb_file, page 8-176.
seg_arb_sequence and seg_arb_wavform:
These more advanced functions can be used by the 4220-PGU and 4225-PMU cards to define a
Segment ARB waveform (see seg_arb_sequence and seg_arb_waveform in Section 8 of the
Reference manual.
NOTE Because of resources necessary to run the Segment ARB engine, an additional
10 ns interval is added to the end of the last segment of a Segment ARB waveform.
During this interval, the output voltage, HEOR, and trigger output values remain the
same as the final value reached in the last segment.
Full arb
NOTE If the firmware for the 4200-PG2 has been upgraded to KITE V6.2, it can be used to
configure and output full arb waveforms (see Firmware upgrade for the 4200-PG2
earlier in this section).
Each channel of the pulse generator can be configured to generate its own unique full arb
waveform. A full arb waveform is made up of user-defined points (up to 262,144).
Each waveform point can have its own unique voltage value. A time interval is set to control the
time spent at each point in the waveform. Figure 1-22 shows an example of a user-defined full arb
waveform. The waveform is made up of 80 voltage points, with the time interval between each
point set to 10 ns.
