SHOW_GATE
Reports the current mode of operation of the ADC gate input. See also SET_GATE_OFF,
SET_GATE_COINCIDENT, and SET_GATE_ANTICOINCIDENT.
Responses:
$FOFF<CR>
Reports the ADC gate is off or ignored.
$FCOI<CR>
Reports the ADC gate is in coincident mode.
$FANT<CR>
Reports the ADC gate is in anticoincident mode.
SHOW_HV
Reports the current high voltage and the status of the high voltage power supply in the form
$Dvvvvvsssssccc
Where vvvvv represents the current output voltage if the high voltage is enabled, or the rear-
panel high voltage setting if the high voltage is disabled. sssss represents the status of the
high voltage bias supply as a 16-bit decimal number with the following bit definitions:
Bit 0 (LSB):
Bias Supply Polarity (0=positive, 1=negative).
Bit 1:
Bias Supply Overload (0=overload, 1=normal).
Bit 2:
High Voltage Enabled (0=disabled, 1=enabled).
Example Responses:
$D0200000003077<CR>
2000 volts, Negative, Not Overloaded, Disabled.
$D0200000002076<CR>
2000 volts, Positive, Not Overloaded, Disabled.
$D0200000007082<CR>
2000 volts, Negative, Not Overloaded, Enabled.
SHOW_INPUT
[0]
Reports the state of the Sample Ready input. See also PAUSE_INPUT,
PAUSE_INPUT_HIGH, and PAUSE_INPUT_LOW.
Responses:
$C00000087<CR>
Sample Ready input is low.
$C00001088<CR>
Sample Ready input is high.
