Channel Voltages

The Channel Voltages tab sheet is the main diagnostics tool. 
Each of the four acquisition channels (not to be mixed up with receiver channels!) can be configured to sample one of the following data sources:

•	Receiver 1 detector voltage (1:1)
•	Receiver 2 detector voltage (1:1)
•	Receiver 1 board temperature (T=voltage*100 [K])
•	Receiver 2 board temperature (T=voltage*100 [K]) 
•	Ambient target temperature (T=voltage*100 [K])
•	Environmental temperature (T=voltage*100 [K])
•	Barometric pressure (P=voltage*1000 [mbar])
•	Rel. humidity (H=voltage*100 [%])

The sample integration time and maximum number of samples are set in General Parameters.
While sampling detector voltages, one can manually turn the noise diodes on and off to check for a correct operation (ND1 and ND2). The detector voltage display can be switched to each receiver channel by selecting its frequency from the related fixed frequency list boxes (Receiver 1 and Receiver 2). 
The channel readings are displayed graphically and also in the Status frame. Data zooming is possible. After stopping the sampling, one can use a ruler to measure the precise voltage at a certain time (↕).
Reset clears the acquisition display and sets the Y-axis to +5 V (maximum).
