Keysight / Agilent / HP E1455A Timing Pod for E1450A Timing Module

The Keysight E1455A Timing Pod is a C-Size VXI accessory that extends the functionality of the E1450A Timing Module by buffering control signals between the module and Device Under Test. This timing pod conditions stimulus signals from the E1450A and buffers response signals - including ten Q lines, a ready line, and a trigger line - back to the timing module, enabling accurate measurements up to two meters from the instrument front panel. Signal delay introduced by the pod and interconnecting cable is automatically compensated when the E1450A is powered. The pod minimizes loading effects on DUT outputs while supporting the E1450A's 160 MHz operation.
