The model 197 is a compact, high performance, low-cost optical chopper, offering features and benefits that are ideal for use in modern photometric systems.

The unit is self contained, comprising a dual aperture chopper blade, motor and the necessary driving electronics. Each aperture provides an independent reference output allowing simultaneous dual frequency operation (10:1 ratio) or dual-path experiments. Frequency control is by a precision internal oscillator set by a 4-digit push-button selector on the unit or by the application of an external AC reference signal. The unit is powered via a remote line power supply.

Mounting holes are provided in the base and right-hand side of the housing (viewed from the front) to allow for mounting the model 197 onto an optical bench or support rod.

  Settling Time

 

7 s nominal at 1 kHz from switch-on;
9 s nominal for frequency change from 150 to 3000 Hz;
30 s nominal for frequency change from 3000 to 150 Hz
Outputs Sync Out 1 10 V pk-pk squarewave at outer sector chopping frequency, 150 - 3000 Hz
  Sync Out 2 10 V pk-pk squarewave at inner sector chopping frequency, 15 - 300 Hz
  Connectors BNC
  Impedance 10 kW. Note that although the output voltage is 10 V pk-pk, the high output impedance means that the outputs can be directly connected to the Reference Frequency input of any SIGNAL RECOVERY lock-in amplifier without causing problems.
