Function generator issue with 4 power channels #252

Closed prasimix closed 2 years ago

prasimix commented 3 years ago

Reported on Discord by Mike G:

If you are using 2 dcp405 and one channel of the dcm224 all is fine, if you enable the other channel of the dcm224 (in other words now have 4 channels selected in the function generator) the dcp in slot2 suddenly increases frequency by a crazy amount, 0.5Hz to 686Hz according to my meter, deselecting any one (either slot1 or either of the DCM channels) channel in the function generator, slot2 resumes normal frequency(0.5Hz), reselecting the 4th channel upsets slot 2 again.
