bPAD+VR

bPAD+ with an analogue output for pulses or count rate, e.g. for flow instruments

Enhanced version of the bPAD+ in which the analogue output can deliver either the pulse signal or a voltage proportional to the discriminated count rate. This is useful, for example, in flow count-rate instruments and HPLC systems.

Operating modes: Differential and integral1
Discriminator: Upper and lower level discriminator, 2,048 steps1
Gain: ×1–×16 (×1–×256 on request)1
Signal outputs: TTL-compatible pulse output of programmable duration1
