Detailed introduction

For transmitting and blocking analog signals in the range +0.2 to +10 V
Coincident or anti-coincident gated Ungated or Gated
External or internal control of gate pulse width

The ORTEC Model 426 Linear Gate offers variable gate duration and its width is controlled by a front panel mounted single turn potentiometer.

More information +

Nominal gate duration is 0.3 to 4 μs. The operation of the linear gate is controlled by a positive start pulse. It can be used to select or suppress linear signals based on selected compliance or timing requirements.

ORTEC model 426 has two operating modes: all input signals without start pulses are blocked, or without inhibiting signals, all signals are passed. The suppression signal can be fed to the front panel "Enable" connector for pulse suppression operation or to the "DC Suppression" connector for DC or continuous suppression operation. DC rejection mode provides external control of the gating period.
