The Agilent E1332A 4-Channel Counter/Totalizer is a B-size, 1-slot, register-based VXI device. It provides seven counter functions: frequency (up to 4 MHz), period average, pulse width, time interval, totalize, gated totalize, and up/down count.

With this module, you select either isolated or direct inputs through software commands. You can connect a total of eight channels to one counter card (only four can totalize simultaneously) by multiplexing between four isolated channels and four non-isolated channels. The digital input low-pass filter is also software selectable with Pass Frequency in 16 binary steps from 4 Hz to 131 kHz. It filters out the high-frequency noise of input signals, such as the bounce of mechanical switches.
