6.2. ARC Management configuration for HPS ≥ 1.5 kW
The following example shows how to configure the ARC management to a full ARC recovery of 200 ms. For more information
about the ARC management, refer to the devices hardware manual.
The ARC management settings are permanently stored in the processors internal flash and are therefore restored after power-
on. Therefore these commands only need to be sent once.

6.3. Controlling HFS devices
6.3.1 Introduction
High voltage devices of the device class HFS combine a power HV device of series HPS
≥
1.5 kW with one or two integrated
filament supplies. The main device is internally divided into different channels. The channel assignment is described in table 11.

Table 11: Channel assignment in HFS devices
To access the channels 6...9, the SCPI commands provide an extended syntax. They get a channel suffix containing the channel
number appended, as shown below:
•
Write commands: „:VOLT 500“ becomes „:VOLT 500,(@0)“ (Suffix appended with comma)
•
Read commands: „:MEAS:VOLT?“ becomes „:MEAS:VOLT? ˽ (@0)“ (Suffix appended with space)
To access channel 7, the suffix would be (@7) instead.
All channel instructions described in section 6 can be applied to the different channels. Furthermore, commands for
parametering the FPS devices exists. These are described in the next chapter.
