1. PRODUCT INTRODUCTION
The intelligent counters are measuring frequency and period from
the range of 0.01Hz to 120MHz on channel A, and 50MHz to
1.3(2.7)GHz on channel B.
The products also provide special features of high resolution and
sensitivity for value reading expediency.

3. PRECAUTIONS BEFORE OPERATION

3-1.Unpacking the Instrument

Instructions for unpacking and inspecting the instrument for damages during transportation.

3-2.Checking the Line Voltage

Guidance on checking and selecting the correct line voltage and fuses for the instrument.

3-3.Equipment Installation and Operation

Ensuring proper ventilation and adherence to specifications for safe and effective equipment operation.

4. PANEL INTRODUCTION

Input and Signal Controls

Controls for input selection, coupling, attenuation, low pass filter, frequency, and period modes for channels A and B.

Measurement and Trigger Controls

Controls for power, reset, gate time adjustment, and trigger level settings for measurement operations.

Display Indicators and Units

Indicators for measurement units (Hz, S), exponents, display status, and overflow conditions.

5. APPLICATION

Signal Measurements

Measure frequency from 0.01Hz-120MHz (Ch A) and 50MHz-1.3(2.7)GHz (Ch B), and period for Ch A.

Gate Time Settings

Adjustable gate time (10ms-10s or 1 period) affects sampling rate and resolution. Knob controls update speed or freeze display.

Trigger Level Adjustment

Adjust trigger voltage for Ch A input signal (±2.5V×ATT); knob can function as auto-trigger.

6. MAINTENANCE

6-1. Standard Method for Calibration

Procedures for calibrating input offset voltage, standard oscillator, and hysteresis bias voltage.

6-2. Cleaning

Instructions for cleaning the instrument using mild detergent and water, avoiding harsh chemicals.
