The Sencore SS137 Sweep Circuit Analyzer manual provides detailed instructions on setting up and operating the device to troubleshoot TV sweep, sync, and high voltage circuits dynamically, with the TV turned on. It covers various checks such as substituting oscillators, measuring voltages and currents, and testing components like the horizontal output transformer and deflection yoke to pinpoint and resolve issues efficiently.
Manual Overview
The Sencore SS137 Sweep Circuit Analyzer is designed for troubleshooting TV sweep, sync, and high voltage circuits dynamically, meaning tests are performed with the TV powered on. This approach is crucial because components may fail under operational conditions despite appearing functional in out-of-circuit tests. The analyzer is particularly useful for diagnosing issues in the horizontal and vertical sweep circuits, which are historically challenging due to their complexity and interaction. The SS137 allows for substitution testing of oscillators and yokes, and it provides a method to check the horizontal output transformer under full power, using a calibrated meter to assess performance. The device includes a universal substitute oscillator section with controls for frequency and amplitude, and it offers various external meter ranges for voltage and current measurements. The SS137 also features a large storage compartment and a distortion-free mirror for viewing adjustments. Understanding the controls and functions of the SS137 is essential for efficient troubleshooting and repair of TV circuits.
Quick Issues Covered
- Diagnose horizontal sweep issues with dynamic testing under full power.
- Check vertical oscillator and output with substitute signals.
- Use schematics for efficient circuit tracing and fault isolation.
Overview

Sencore SS137 Sweep Circuit Analyser Overview
The Sencore SS137 Sweep Circuit Analyser is a precision electronic test instrument designed to evaluate and analyze the frequency response of electronic circuits and components. It generates a variable frequency signal that sweeps across a defined range, allowing technicians and engineers to identify circuit characteristics, detect faults, and verify performance. This device is essential for troubleshooting and servicing radio frequency (RF) and audio frequency (AF) circuits in communication equipment, amplifiers, and other electronic systems.
Main Features and Specifications
- Frequency sweep range: 10 Hz to 1 MHz
- Adjustable sweep rate for detailed analysis
- High output signal stability and accuracy
- Built-in signal level control for precise testing
- Clear analog display for real-time waveform observation
- Compact and rugged design suitable for field and bench use
- Compatible with a wide range of electronic components and circuits
Basic Usage and Operation Tips
To operate the Sencore SS137, connect the output terminals to the circuit under test. Power on the unit and set the desired frequency sweep range and sweep rate using the front panel controls. Observe the response on the connected measuring device or the analyser’s display. Adjust signal levels as needed to prevent distortion or overload. Use the sweep function to identify frequency-dependent behaviors such as resonance, attenuation, or signal loss. Always start with the lowest signal level and gradually increase to avoid damaging sensitive components.
Troubleshooting and Maintenance
If the analyser fails to produce a stable sweep signal, verify all cable connections and ensure the power supply is stable. Check for blown fuses or damaged internal components if the device does not power on. Regularly clean the exterior and control knobs to prevent dust accumulation. Calibration should be performed periodically by qualified personnel to maintain measurement accuracy. Store the unit in a dry, dust-free environment to prolong its operational life.
Safety Reminder
Always disconnect the analyser from power before performing any maintenance or internal inspection. Avoid exposing the device to moisture or extreme temperatures. Use caution when connecting to high-voltage circuits to prevent electric shock. Follow all local safety regulations and manufacturer guidelines to ensure safe and reliable operation.
