The VT1511A 4-channel Transient Strain SCP provides 4 channels of strain measurements. It provides strain completion circuitry and excitation voltages, a programmable filter, and sample and hold circuitry. The sample and hold inputs sample all four channels simultaneously to reduce the skew introduced by scanning.

The low-pass filter on each sample and hold channel is a 6th order Bessel active RC filter used to provide alias protection and noise reduction. The filter cutoff frequencies are 1kHz, 500Hz, 250Hz, 100Hz, and 15Hz. The SCP can be wired for measuring excitation voltages at the bridge connection (remote sense) or locally (terminal module). Excitation voltages of 0V, 1V, 2V, 5V, or 10V are available on each channel. The SCP provides a voltage gain of 0.5, 8, 64, or 512 for each channel. This SCP takes two adjacent slots in the VXI module.
