Pull or turn the Amplitude knob to safely regulate your voltage ceiling between 2V and 20V P-P. If testing sensitive components, engage the to drop signal power by up to 40dB. 3. Utilizing Advanced Functions

: Pulling or adjusting this knob alters the standard 1:1 duty cycle. This shifts a square wave into a variable pulse width wave, or a symmetric triangle wave into a sawtooth ramp.

Operating the Protek B801 efficiently requires understanding its control topology. The hardware relies on tactile knobs and switches that interact directly with its internal analog circuitry. 1. Frequency Selection & Fine Tuning

Select your primary waveform geometry (Sine, Square, or Triangle) using the physical layout push-buttons.

the SYMMETRY dial away from CAL to warp the duty cycle up to a 4:1 ratio. Use the formula

Includes DC offset control and a Voltage Controlled Frequency (VCF) input.

Monitor the oscilloscope while twisting the symmetry knob to achieve your targeted duty cycle or rise-to-fall ratio.

The Protek B801 is more than just a basic multimeter. Understanding its specs will help you get the most out of it once you have the manual in hand.
