discriminator is in the FIXED mode. Changing the
scan step during a scan will affect the level for the
next count period and all those that follow.
DL i { ,v }
The DL command sets and reads the discriminator
levels. i = 0,1, or 2 designates discriminator A,B,
or T and is required. If v is included, the selected
discriminator level is set to v Volts where -0.3000
<= V <= 0.3000. The resolution is 0.0002 V (0.2
mV). If v is absent, the selected discriminator level
is returned. If the discriminator mode is SCAN,
the DL command sets and reads the starting value
of the level. Changing the level during a scan will
cause the level to be set to the new value on the
next count period. Note that the scan is not reset.
Reading the level during a scan always returns the
starting value, not the current value.
DZ i
The DZ command returns the level of
discriminator i during a scan. i = 0,1, or 2
designates discriminator A,B, or T and is required.
If discriminator i is in the SCAN mode, its current
level during a scan is read. If the counters are in
reset or the discriminator is in the FIXED mode,
the DZ command returns the starting value for the
level (same as DL command). The DZ command
is a read only command.
PM i { ,j }
The PM command sets and reads the rear panel
PORT1 and PORT2 D/A output modes. i=1 or 2
to select PORT1 or PORT 2 and is required. If j is
included, the mode is set to FIXED, j=0, or
SCAN, j=1. If j is absent, the mode is returned.
The mode may be changed during a scan. If it is
changed to SCAN, the level begins scanning from
the start value on the next count period. If it is
changed to FIXED, the level returns to the start
value immediately.
PY i { ,v }
The PY command sets and reads the PORT1 and
PORT2 scan steps. i=1 or 2 to select PORT1 or
PORT 2 and is required. If v is included, the scan
step is set to v Volts where -0.500 <= v <= 0.500.
The resolution is 0.005 V (5 mV). If v is absent,
the scan step is returned. The scan step may be set
and read even if the selected port is in the FIXED
mode. Changing the scan step during a scan will
affect the level for the next count period and all
those that follow.
PL i { ,v }
The PL command sets and reads thePORT1 and
PORT2 output levels. i=1 or 2 to select PORT1 or
PORT 2 and is required. If v is included, the
output level is set to v Volts where -10.000 <= v
<= 10.000. The resolution is 0.005 V (5 mV). If v
is absent, the output level is returned. If the Port
output mode is SCAN, the PL command sets and
reads the starting value of the level. Changing the
level during a scan will cause the level to be set to
the new value on the next count period. Note that
the scan is not reset. Reading the level during a
scan always returns the starting value, not the
current value.
PZ i
The PZ command returns the level of the PORT1
and PORT2 outputs during a scan. i=1 or 2 to
select PORT1 or PORT 2 and is required. If the
selected port is in the SCAN mode, its current
level during a scan is read. If the counters are in
reset or the output is in the FIXED mode, the PZ
command returns the starting value for the level
(same as PL command). The PZ command is a
read only command.
GATES
GM i { ,j }
The GM command sets and reads the gate modes. i
= 0 or 1 designates A gate or B gate and is
required. If j is included, the selected gate is set to
CW, j=0, or FIXED, j=1, or SCAN, j=2. If j is
absent, the mode of gate i is returned. The mode
may be changed during a scan. If it is changed to
SCAN, the delay begins scanning from the start
position on the next count period. If it is changed
to FIXED, the delay returns to the start position
immediately. If it is changed to CW, the gate
immediately changes to continuously on.
GY i { ,t }
The GY command sets and reads the gate delay
scan step. i = 0 or 1 designates A gate or B gate
and is required. If t is included, the selected gate
scan step is set to t seconds where 0 <= t <=
