The Dual-Channel Sampler performs time expansion of the I- and Q-channel baseband signals from the radar receiver in order to allow further processing and display. It has three switches to select the system observation range, as well as control knobs for adjusting the system range origin, the balance of the I- and Q-channel output signals, and the DC offsets at the I- and Q-channel outputs. A time base output is provided to obtain an A-scope display on a conventional oscilloscope.

Unregulated DC power is automatically supplied to the Dual-Channel Sampler through self-aligning connectors when it is installed on the Power Supply / Antenna Motor Driver
