vhq205l(), HV power supply

This function controls the VHQ205L HV power supply of ISEG (2x 5 kV, 1 mA).

Write:
$ret = vhq205l( "hv1", $keyword, $value);
Read:
$ret = vhq205l( "hv1", $keyword);

 D0 Output voltage channel A is zero

 D1 Control switch, 0 -> DAC, 1 -> manual

 D2 Output polarity, 1 -> positive

 D3 HV on (0)/off (1)

 D4 Kill switch, 0 -> disabled

 D5 Output voltage derivative, 1 -> rising

 D6 Status V-out, 1 -> V-out changing

 D7 Error on channel A, 1 -> error

 D8 ... channel B

 register_2, R

 D0 Timeout error

 D1 I-out > I-max

 D2 V-out reached set point

 D3 A front panel switch has been changed

 D4 Ratio V-setpoint/V-max > 1

 D5 External INIHIBT is/was active

 D6 Exceed/ed V-max or I-max

 D7 Quality of V-out not garanteed

 D8 ... channel B

 set_point, R/W

e.g.:
$ret = vhq205l( "hv12", "actual_value");
$ret = vhq205l( "hv12", "set_point", "1234");

If a new set point is specified, Online also starts the ramp and waits for the voltage to reach the final value.
