Page 4: Product Description
1. PRODUCT DESCRIPTION 1-1. Introduction This reciprocal UNIVERSAL COUNTER series are microprocessor controlled instruments for frequency measurements at high resolutions within a short period of time. The high resolution is due to uniquely developed LSI as well as the expanding/reciprocal systems. It covers a frequency range from 0.1 Hz to 2.4 GHz based on 10 MHz time base T.C.O (temperature controlled oscillator) and also featuring, ... -

Allow more than 30 minutes for the unit to warm up so that it is stabilized and ready for use. 3. OPERATION 3-1. Controls, indicators and connectors FIG(2) FRONT PANEL GATE INDICATOR : The gate light, when lit, indicates the main gate is open and measurement in progress. - Page 11 the knob out and rotating it varies the level from negative to positive around the mid point. INPUT C, BNC : Input for frequency measurements above 80 MHz Female BNC connector terminated in 50 Ω. LOW PASS FILTER : With this switch pushed in, the input B is routed through a SWITCH(LPF) low-pass filter with -3 dB point of approximately 100 kHz.

Page 16: Time Interval Measurement(A-B)
3-6. Time Interval Measurements(A→B) In time interval mode, unit measures the elapsed time from a selected edge of the input A waveform to a selected edge of the input B waveform. For a stable reading, the two input signals should be related to each other such that this time interval remains reasonably constant from one measurement to the next. -
Page 17: Ratio Measurement (A/B)
Frequency Ratio Measurements (A/B) 3-7. In this mode of operation, the counter displays the ratio of the frequency applied to input A to the frequency applied to input B. The input A frequency should preferably be equal to or greater than that of input B. And both frequencies must be within the limits given in the "SPECIFICATIONS"... -

5. OTHERS 5-1. BNC Cable Considerations Accuracy of radio frequency measurements can be affected by connections between signal source and counter. Main considerations are standing waves and shunt cable capacitance. Standing wave is usually present due to reflections when a transmission line is not terminated in its characteristic impedance. -
Page 21: Line Frequency Measurements
5-3. Line Frequency Measurements Use of the attenuator, low pass filter, and/or x10 probe is advisable when measuring line frequency because the high amplitude signal and noise can cause wrong counting. WARNING USE CAUTION IN MEASURING THE LINE FREQUENCY OF AN AC OUTLET. USING THE PROBE TIP ONLY, MEASURE BOTH SIDES OF THE LINE. - Page 22 Limited One-Year Warranty B&K Precision Corp. warrants to the original purchaser that its product and the component parts thereof, will be free from defects in workmanship and materials for a period of one year from the data of purchase.
