1.4. Status and Event generation
Channel as well as Module have status and event registers. Both registers contain similar condition bits. The difference between
both register types is, that status bits are set and cleared by the device according to the current conditions. Event bits, however,
are only set by the device and must be cleared explicitly by the user (like a latch).
For example, the Status bit is Constant Current indicates that the channel
is now
in constant current mode. The Event bit Event
Constant Current in contrast indicates, that the channel has been (or still is) in constant current mode since the last clearing of
this bit.
It is thereby possible to clear all status flags at once or to just clear individual bits. In general it is not possible to clear an event bit
if the corresponding status bit is still set. The status and event registers are described in detail in section 8 Description of control,
status, event, and mask registers.
1.5. Hardware options
Some devices can be attached with hardware options that provide extra functionality. These hardware options can be controlled
with additional SCPI commands. These commands can only be used with a device that has the according hardware option
installed.
A short overview of hardware options is given below. For more information, refer to the
, see
1.5.1 Option VCT (Voltage Compensation by Temperature)
This option can be added to devices NHS or NHR. An external temperature sensor allows a V
set
correction according a VCT factor
and the temperature difference. The VCT features can be accessed with the 5.2.1 Option VCT.
