Can thermocouple measurements be set up on any channel of the 34901A, 34902A and 34908A?

On the 34901A, channels 1-20 may be configured for thermocouple measurements. Channels 21 and 22 are for current measurements only, therefore they can not be configured for thermocouple measurements.

On the 34902A all channels may be configured for thermocouple measurements.

On the 34908A all channels may be configured for thermocouple measurements, but all the lows will be referenced to the same point.
