Tektronix DC508

This Counter is designed to operate in TM 500 / TM 5000 series mainframes and measures frequency from 10Hz to 1GHz

Separate inputs are used for the 10Hz to 100MHz, and 100MHz to 1GHz

A switch selectable frequency resolution multiplier multiplies the resolution by 100 from 10Hz to 25KHz.

This allows resolution of 0.01Hz in 1sec.

On the top right one is a stand by key with that the display can be switched off.

This unit is suitable to measure e.g. the frequencies of the SG504 (output' frequency monitor out ').

A nine digit LED Display shows frequency or total events from 0 to 999,999,999.

The decimal point is automatically positioned and leading zeros suppressed.
