The Channel 2 Alert will report when:
-
The Channel 2 output is higher than 1.08Vrms
-
The Channel 2 output is lower than 0.72Vrms
To adjust the Alert Threshold from the front panel, hold the NEXT and SELECT buttons
down simultaneously for two seconds. The percentage value will begin flashing. To
increase the value, press the SELECT button. To decrease the value, press the NEXT
button.
When the desired value is reached, press the NEXT and SELECT button simultaneously to
leave the settings mode.
The Alert Threshold settings can be modified via the RS232 serial port with the $FLTTHR
command.
For details on the Alert Threshold, see Programmer’s Guide.
2.6 Latch Channel Values
The Latch Channel Values Screen allows the user to save the current channel output
values for use as the Reference Value for Alert settings.
A channel Alert is triggered when a channel output voltage exceeds or falls below a
percentage of the reference value. This reference value is 1.10Vrms as a default, but can
be set by the user.
There are two ways to set the reference voltage. The RS232 serial port allows for setting
an individual channels reference voltage with the $SET command. The user can also use
the Latch Channel Values to take a snapshot of all current outputs and use these as the
reference values.
2.7 PPS Status
