pulse_ssrc
This command controls the high-endurance output relay (HEOR) for each output channel of the PGU.
Usage
int pulse_ssrc(int
instr_id
, long
chan
, long
state
, long
ctrl
);
instr_id
The instrument identification code of the pulse card, such as VPU1 or VPU2
chan
Channel number of the pulse card:
1
or
2
state
Open:
0
Close:
1
(default)
ctrl
How the HEOR will be controlled:
•
Auto (the Segment Arb pulse mode controls the HEOR):
0
(default)
•
Manual (
state
parameter opens or closes relay):
1
•
Trigger out driven (relay state follows the trigger output):

Pulse modes
Standard, Full Arb, Segment Arb
Details
The high-endurance output relay (HEOR) is a solid-state relay (SSR) on each channel of the pulse
card. Note that this setting is independent of the output relay (see
pulse_output
). A simplified
schematic showing the relays is shown here.
