SINE Sinusoidal Single Frequency Gratings
-
Our SINE Sinusoidal Single Frequency transmittance patterns have proved to be very useful for specialized MTF Measurement as well as for such applications as moirè contouring. They are made on film base material with a nominal thickness of 0.175mm. This material is polyester and tends to be somewhat birefringent. The harmonic modulation values are generally 3% or less.

Frequency, Rate Meter, Flow Rate Indicator
-
Two independent scalable pulse-input channels from 0 Hz to 1 MHz. Channels may be combined arithmetically. One channel can display total while other displays rate. High read rate for control applications: AC line frequency can be measured to 50.0000 or 60.0000 Hz in a few line cycles. Ideal for use as a tachometer or readout of a turbine flow meter.

High Frequency Standard Capacitor
GenRad 1403 Series
-
The GenRad 1403 Standard Air Capacitors are stable, three-terminal standards in decimal values from 0.001 pF to 1000 pF. For measurement at 100 pF and below, a three terminal connection increases the accuracy by eliminating the uncertainty in the measurement introduced by the capacitances between the capacitor terminals and ground.
