CARD?
Returns a string representing the active
card type.
“2 CHAN FILTER\n” for a 2 channel filter type
card.
CHAN?
Returns a string representing the active
channel type. This is valid only on channels
of function-based cards.
Channel type: “L8D\n”, “L8E\n”, “L8B\n”,
“L8L\n”, “H8D\n, H8B\n”, etc
FREQ?
Returns a string value representing the
active card/channel frequency setting.
Frequency setting: “10.00KHz”, “10.00 Hz”,
etc.
PRE?
Returns a string value representing the
active card/channel pre-gain setting.
A value from 00dB to 60dB in 5dB
increments.
POS?
Returns a string value representing the
active card/channel post-gain setting.
A value from 00dB to 20dB in 1dB
increments.
FIL?
Returns a string representing the active
card function type setting.
“SUM\n”, “CAS\n” or “DUAL\n”.
CUPL?
Returns a string representing the active
card coupling mode setting.
“AC\n” coupled or “DC\n” coupled.
INPUT?
Returns a string representing the active
card input mode setting.
“SNGL\n” single-ended or “DIFF\n”
differential-ended.
OUTPUT?
Returns a string representing the active
card output mode setting.
“NORM\n” active channel or “BYPS\n” by-
passed channel.
OFFSET?
Returns a string value representing the
active card DC offset setting.
A value from “-100mV” to “100 mV”, for
example: “-05 mV”, “09 mV”, “10 mV”, etc.
BP
Sets the channel configuration of active
card channels to band-pass filter.
Configure two channels as a band-pass filter.
BR
Sets the channel configuration of active
card channels to band-reject filter.
Configure two channels as a band-reject
filter.
DUAL
Sets the channel configuration of active
card channels as independent filters.
Configure the filter card as dual independent
channels.
DC
Sets the coupling mode of an active card
channel to DC.
Set DC coupled mode.
AC
Sets the coupling mode of an active card
channel to AC.
Set AC coupled mode.
BYPS
Sets the output mode of an active card
channel to by-pass.
The channel filter is bypassed.
NORM
Sets the output mode of an active card
channel to normal.
The current channel filter is activated.
SNGL
Sets the input mode of an active card
channel to single-ended.
Set the current channel to the single-ended
mode.
DIFF
Sets the input mode of an active card
channel to differential-ended.
Set the current channel to the differential-
ended mode.
CARD=n
Selects an active card.
Select a card where n is 1, 2, 3 or 4.
CHAN=n
Selects an active card channel.
Select a channel where n is 1 or 2.
FREQ=xyyyxU
Sets the frequency of an active card
channel.
Set the frequency where x can be any
number from 0 to 9 and y can be any number
from 0 to 9 or a . (point). U represents the
units “K” for kilo Hertz or “” (empty) for Hertz.
PRE=xy
Sets the pre-gain of an active card channel.
Set the pre-gain where x can be any number
from 0 to 6, and y can be 0 or 5. Leading
zeroes may be dropped.
