Is the crate (and implicitely all registered channels) a real device? - implicit via crate config isRealDevice

Does the channel support only one ramp rate singleRampRate singleRampRate
(bool, default false)

maximum current supported by board queried currentS_max_manual
CAEN does not allow to query that property
-
polarity of channel queired polarity
CAEN does not allow to safely query that property

demanded voltage on the device (Sollpannung die auf dem Gerät gesetzt ist) setVoltageHardwareI setVoltageHardwareI - Es gibt bei CSCO immer wieder Überlegungen, ob der Sollwert nochmal mitgeschickt werden soll. Ich persönlich finde es überflüssig, ausser vielleicht, es ist der aus dem Gerät ausgelesene Sollwert. Aber da gibt es viele Meinungen.

MPOD::Detailed Status Bits

In der MPOD Klasse werden momentan diese Bits ausgelesen und gesetzt. Teilweise verhalten sich die Bits nicht wie erwartet, z.B. “outputOn” zeigt nur true, wenn der Kanal eingeschaltet ist UND eine Spannung anliegt. Wenn der Kanal eingeschaltet ist aber auf 0V steht, ist das Bit false. Auf manchen Karten ist das outputAdjusting Bit immer an.

ACHTUNG: Bei den Failure Bits bedenken, dass gilt: ERROR_ON_FALSE und WARNING_ON_FALSE, d.h. bit gesetzt bedeutet alles OK!
