9.2 Option -HV: Additional AC Voltage Range
The -HV option provides an additional AC only output voltage range of 0-400
VRMS. There is no equivalent 200 VRMS range associated with the -HV option
but the standard 0-150 V RMS and 0-300 V RMS remain available even if the -
HV option is installed.
If the -HV option is installed, there will be three voltage ranges that can be
selected from the PROGAM 1 menu. (150/300/400). Other than the range
values, all other operations remain the same. Note however that the -HV range
is AC coupled and as such offers no DC output capability. Thus, whenever the
400 V range is selected, the output mode is automatically set to AC MODE and
other modes cannot be selected.
Since the –HV option range is AC coupled, the lower frequency limit on the –HV
range is 45 Hz and not the 16 Hz that applies to the standard 150/300V ranges.
The upper frequency limit remains the same.
Arbitrary waveforms
As stated before, the –HV (and –XV) range is AC (transformer) coupled and as
such cannot pass any DC component from the waveform generator. This means
that any arbitrary waveform created by the user that is to be used in the –HV
range cannot have any DC offset. The MX firmware will generate an error
message is an attempt is made to select a custom waveform with DC offset
while in the –HV range.
