27708A Octal-Channel Programmable AC/DC  Amplifiers

The 27708A card provides eight channels of high performance AC/DC amplifiers.

The Precision 27708A octal programmable amplifier card allows for up to 128 channels in one 28016B-M3 chassis. Systems beyond 128 channels may be accommodated by multiple mainframes controlled from a single controller.

The 27708A provides overall gain of x1/16 to x4096 with 0.05% resolution. A balanced differential input results in outstanding rejection of common-mode interference. Low noise and low drift insure data integrity will be maintained. Output overload detectors alert the user to possible non-linearities caused by internal amplifier overloads. Optional features include a programmable AC/DC coupling and a constant current source for piezoelectric transducers. Test and monitor busses allow the 27708A to integrate seamlessly with the 28000 Test Subsystem for built-in performance verification.
