Line Injector
J2120A
-
While the injection transformer is a very wideband adapter, it is not useful for measuring ripple rejection (PSRR) of a power supply or even an opamp. This is because the attributes that make the injection transformer perform so well also result in a transformer that is intolerant of DC current. Even very small DC currents (5mA or less) can greatly reduce the signal capacity or even totally saturate the transformer. For this reason, the Picotest line injector (J2120A) is another essential test adapter.

PC/104 Input/Output Module providing 96 lines of digital I/O
PCM-UIO96C-16
Digital I/O Module
The PCM-UIO96C-16 is a highly versatile PC/104 input/output module providing 96 lines of digital I/O. One important feature of this card is its ability to monitor 48 of the 96 lines for both rising and falling digital edge transitions, latch them, and then interrupt the host processor notifying that a change-of-input status has occurred. This is an efficient way of signaling the CPU of real-time events without the burden of polling the digital I/O.
