B.66 [SOURce:]LIST:SAMPle:VOLTage COMMAND
Syntax:
Short Form: LIST:SAMP:VOLT average,value
Long Form: LIST:SAMPle:VOLTage average,value
where:
average = number of measurements = integer: 2,4,8,16,32,64,128 or 256
value = programmed current (Amps) for current list, or programmed voltage (Volts) for voltage list.
Description: Samples output voltage. <Value> is either programmed current in Amperes, or programmed voltage
in Volts. <Average> can only be 2, 4, 8, 16, 32, 64, 128 or 256. Entering a number other than those
permitted results in the average being set to the next lowest permitted number. The actual number of
points added to the list is <average>. The samples are taken within the window established by <aver-
age>. The timing of the first sample is not exact. The sample duration must be established by the
LIST:SET:SAMP command, otherwise a -221 "Settings conflict" error will result
This command must be preceded by LIST:CURR, LIST:VOLT or LIST:SET:SAMPLE command, other-
wise a -221 "Settings conflict" error will result. The entries on the dwell list must match the values on
the current or voltage list, otherwise a -226 "Not Same Length" error will result. Only eight samples
may be taken in a list. If more than eight LIST:SAMP:CURR or LIST:SAMP:VOLT commands are
included in the list, a -223 "Too Much data" error results. Also, note that each sample uses one of the
points in the waveform table; if the total number of points in the waveform exceeds 3933, -223 "Too
Much data" error results. (See Figures B-6 and B-7.)
B.67 [SOURce:]LIST:SAMPle? QUERY
Syntax:
Short Form: LIST:SAMP?
Long Form: LIST:SAMPle?
Returns:<INT_VALUE>,<INT_VALUE>....<INT_VALUE>[V|C]
Description: Returns a comma-separated list of numbers representing points, followed by V or C. The point
listings are determined by the settings of LIST:SAMP:CURR and LIST:SAMP:VOLT commands. The
sample(s) occur after the points indicated. The type of list is indicated by V (Voltage) or C (Current).
(See Figures B-6 and B-7.)
B.68 [SOURce:]LIST:SET:SAMPle COMMAND
Syntax:
Short Form: LIST:SET:SAMP value
Long Form: LIST:SET:SAMPle value
where value = sample pulse duration, between 0.00025 and 0.034 (seconds)
Description: Establishes sample pulse duration. This command must be used when measuring a sample, but
must only be issued once, otherwise a -100 "command error: will result. (See Figures B-6 and B-7.)
B.69 [SOURce:]LIST:SET:SAMPle? QUERY
Syntax:
Short Form: LIST:SET:SAMP?
Returns: <exp_value>
Description: Returns sample pulse duration. Returns sample pulse duration set by LIST:SET:SAMP command,
between 0.00025 and 0.034 second.
mand error" results.
B.70 [SOURce:]LIST:SET:TRIGger COMMAND
Syntax:
Short Form: LIST:SET:TRIG <time>,<transistor>
Long Form: LIST:SET:TRIGger <time>,<transistor>
<time> = 0.00025 to 0.034 (Seconds)
<transistor> = ON or OFF
Description: Establishes output trigger pulse-width. Used to set the pulse-width at a) the BOP output and b) a
trigger provided by the BOP to trigger an external device. The Output Off flag at EXT PROTECT
PORT, pins 5 and 6 (see Table 2-4) represents the trigger pulse timing instead of output on/off status
until LIST:CLE is issued. See Figure B-7 for example. The pulse width, between 0.00025 to 0.034
(Seconds) is established by <time>. When <transistor> = ON, the transistor across EXT PROTECT
PORT pins 5 and 6 is on (conducting) while pulse is active. When <transistor> = OFF, the transistor
across EXT PROTECT PORT pins 5 and 6 is off while pulse is active.
