The HP 8111A is a compact pulse/function generator that covers a frequency range from 1 Hz to 20 MHz with 3‑digit resolution. It offers multiple operating modes—including normal, trigger, gate, VCO and optional burst—plus a digital display for all parameters and error detection for reliable operation.
Key features include variable pulse width down to 25 ns, adjustable duty cycle up to 999 kHz, and output amplitudes from 1.6 mVpp to 16 Vpp. The instrument is designed for bench and service use, with a 50 Ω load specification, wide temperature range, and optional accessories such as burst mode and rack‑mount kits.
