Remote Programming – Command List
40
data points completed so far during the current
scan and is shown in the brackets on the N
PERIODS menu line. The NN command is a read
only command.
NE { j }
If j = 0, the NE command sets the scan end mode
(AT N) to STOP. If j = 1, the mode is set to
START. The scan end mode may be changed at
any time. If j is absent, the scan end mode is
returned.
DT { x }
The DT command reads and sets the dwell time. If
x is absent, the dwell time is returned. If x is
included, the dwell time is set to x seconds where
2E-3 <= x <= 6E1. If x = 0, the dwell is set to
EXTERNAL. Only the most significant digit of x
is used so "DT 2E-3" , "DT .0022" , "DT 2.2E-3"
all set the dwell to 2 ms.
AS { j }
The AS command reads and sets the front panel
D/A output source. If j is absent, the D/A source is
returned. The parameter j may only be included if
the counting mode is A,B FOR T PRESET. In this
case, j=0 or 1 selects A or B. In all other modes,
the D/A output follows the count display. The
source may be read in all modes.

AM { j }
If j is included, the AM command sets the D/A
output scale. If j is absent, the D/A output scale is
returned.

SD { j }
If j = 1, the SD command sets the count display
mode to HOLD. If j = 0, the display mode will be
CONTINUOUS. If j is absent, the display mode is
returned.
LEVELS
TS { j }
If j = 1, the TS command sets the gate trigger
slope to FALL or negative. If j = 0, the gate trigger
slope is set to RISE or positive. If j is absent, the
gate trigger slope is returned.
TL { v }
If v is absent, the TL command returns the gate
trigger level. When v is included, the trigger level
is set to v Volts where -2.000 <= v <= 2.000. The
resolution is .001 V.
DS i { ,j }
The DS command sets and reads the discriminator
slopes. i = 0,1, or 2 designates discriminator A,B,
or T and is required. If j is included, the selected
discriminator slope is set to RISE, j=0, or FALL,
j=1. If j is absent, the slope of discriminator i is
returned.
DM i { ,j }
The DM command sets and reads the
discriminator modes. i = 0,1, or 2 designates
discriminator A,B, or T and is required. If j is
included, the selected discriminator is set to
FIXED, j=0, or SCAN, j=1. If j is absent, the
mode of discriminator i 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.
DY i { ,v }
The DY command sets and reads the discriminator
scan step size. i = 0,1, or 2 designates
discriminator A,B, or T and is required. If v is
included, the selected discriminator scan step is set
to v Volts where -0.0200 <= v <= 0.0200. The
resolution is 0.0002 V (0.2 mV). If v is absent, the
selected discriminator scan step is returned. The
scan step may be set and read even if the selected
