:INPut :HYSTeresisPM6685
8 «<Decimal data>|MAX |MIN»
Sensitivity
The sensitivity setting on the front panel is called HYSTeresis from the bus. The
range is 27.12 mV to 75.4 V. This setting has no effect unless autosensitivity is
turned off, see the following page.
Note that the sensitivity setting is coupled with the hysteresis setting according to
the formula:
Trigger Level Hysteresis+
<
2
377057. K
Parameters: <Decimal data> is a number between 27.12E-3 and 75.4.
MAX gives +75.4 V, MIN gives +2.7 mV
When using MAX as data, the counter always tries to set the hysteresis to +75.4 V.
Unless the Trigger level is set to 0, this setting is impossible, and the counter will
return an error message.
Returned format: <Decimal data>
Example:
SEND→
:INP:HYST 8 0.5;HYST:AUTO 8 0
This example sets the sensitivity to 0.5 V and switches off autosensitivity.
*RST condition 0.65 V (but controlled by Autotrigger since AUTO is on after *RST)
