[SENSe:]TOTalize:THReshold
Syntax [SENSe:]TOTalize:THReshold <value>[,(@<ch_list>)]
[SENSe:]TOTalize:THReshold? [(@<ch_list>)]
Description
Set or query the threshold values for the specified TOT channels.
Parameters
Name
Type
Range
Default
<value> Numeric
Any numeric value between -12V and +12V,
the resolution is 0.001 V
2.5V
<ch_list>
Channel
List
One or more channels (only for the TOT
channels), the rules are as follows:
(@107): channel 07 on the module in Slot1;
(@107:108): channel 07 through 08 on the
module in Slot1;
(@107:108,307): channel 07 through 08 on
the module in Slot1 and channel 07 on the
module in Slot3.
If the parameter
is omitted, this
command will be
applied to the
whole scan list.
Explanation  The totalizer channels are numbered "S05" to "S08"; wherein, S is the number of the
slot. This function is only applicable to “S07” and “S08” TOT channels. For TOT
channels “S05” and “S06”, the threshold is fixed at CMOS 3.3 V.
 The instrument starts counting when the rising edge or falling edge of the input signal
passes through the specified threshold.
 The instrument configures the threshold to 2.5V automatically after a Factory Reset
(send the
*RST command). An Instrument Preset (send the SYSTem:PRESet
command) or Card Reset (send the
SYSTem:CPON command) does not affect the
current setting.
Return
Format
The query returns the threshold in scientific notation for each totalizer channel specified.
Multiple return values are separated by commas.
Example TOT:THR 5,(@207)
TOT:THR? (@207)
The query returns +5.000000000E+00.
