Connect your BNC cable to the Output port. Use the TTL Sync Output if you need a standard 5V square wave for triggering other instruments.
The B801 typically requires about 20 minutes of warm-up time to reach its rated frequency stability of 0.1%. Support - Protek Instrument
Based on standard Protek function generator workflows, here is how to get started: protek b801 manual link
View the Protek B801/B803 Technical Datasheet via Mouser Electronics for a full breakdown of frequency ranges, output characteristics, and waveforms.
The B801 features a 100:1 tuning control on each range. Use the coarse dial for large jumps and the fine-tuning knob for precise adjustments. Connect your BNC cable to the Output port
The manufacturer's Support Page often hosts manuals for legacy instruments like function generators and oscilloscopes.
Check the DC Offset knob. If it is pushed or pulled incorrectly, it might be clipping the signal or shifting it out of the visible range of your oscilloscope. Distorted Square Waves: Ensure you are using a Support - Protek Instrument Based on standard Protek
Ensure the AC input voltage matches your local power source before connecting the line power.
You can control the output frequency externally by applying a DC voltage to the VCF input on the rear or front panel. Common Issues to Watch For
The B801 is known for its versatility in generating different signal types. Key specs include: Specification Details Sine, Square, Triangle, Pulse, Ramp Frequency Range 0.02Hz to 2.0MHz (across 7 ranges) Output Amplitude 2V to 20V P-P (open circuit) Output Impedance DC Offset Variable from Distortion Less than 2% for sinewaves Operating Instructions & Troubleshooting
