Racal Frequency Counter Type 9024

INTRODUCTION

The Type 9024 is a compact, Lightweight Frequency Period Meter styled in the Racal 9000 series image, being slim-line and of full rack width.

It has a frequency measuring capability covering the range 10Hz to 600MHz, this is achieved using two input channels each with its own switched attenuator.

Signals in the range 10MHz to 600MHz are applied to the Channel ‘A’ input where a Pre-Scaler Assembly of advanced design provides decade division.

The Channel ‘B’ input is used when measuring frequency in the range l0Hz to 60 MHz and also for Period Measurement in the range 10 Hz to 3 MHz.
