Overview
The Pendulum Instruments A600 is a general-purpose broadband single-channel high voltage linear amplifier with a fixed gain of 100, amplifying a source of no more than ±3 V to a bipolar high voltage output of ±300 V (a peak voltage of ±300 Vp, that is 600 Vp-p). Bandwidth covers DC to 1 MHz (at 100 Vpp) and holds DC to 350 kHz at maximum output voltage, the slew rate reaches 500 V/µs, the continuous output current limit is 75 mA and maximum output power is about 30 W. Output impedance is below 0.1 Ω, input impedance is 1 MΩ (in parallel with 30 pF), and a built-in 15 mA microfuse protects the input — it opens automatically when the input voltage exceeds 500% of the rated maximum. The maximum capacitive load is set at the factory to 300 pF (corresponding to a 300 V/µs slew rate limit), and every electrical characteristic meets the strict linearity and stability requirements of high voltage test and measurement.
Key features
- ±300 V bipolar high voltage output — ±300 V bipolar output (600 Vp-p) with a fixed voltage gain of 100 drives a high voltage application straight from a source of ±3 V or less, with no extra signal conditioning.
- Broadband, DC to 1 MHz — Frequency response extends from DC to 1 MHz (at 100 Vpp) with a slew rate of up to 500 V/µs, so high-frequency signals keep excellent waveform fidelity even under high voltage drive.
- Low output impedance design — An output impedance below 0.1 Ω drives low-impedance loads effectively and holds the output voltage steady, suiting piezo actuators, MEMS and other highly capacitive or low-resistance loads.
- Layered input protection — A built-in 15 mA microfuse opens automatically when the input voltage exceeds 500% of the rated maximum, and the factory-set maximum capacitive load of 300 pF prevents damage from an over-large capacitance.
- A genuinely general-purpose amplifier — Suited to research institutes, R&D laboratories and component manufacturing, it drives piezo actuators, MEMS, OLED, liquid crystal display devices and many other high voltage test applications.
- Dual-channel upgrade available — The A600 can be upgraded to the dual-channel A600D, in which two independent A600 amplifiers share a ground reference and power supply — for advanced measurements needing differential or two-channel synchronous drive.
Typical applications
- Driving piezo actuators for nanometre-scale precision positioning — In atomic force microscopy (AFM), adaptive optics and precision vibration control systems, a piezo actuator needs a steady bipolar high voltage signal to use its full travel. The A600 provides ±300 V peak (600 Vp-p) of linear output, amplifying the low-amplitude signal of an arbitrary waveform generator (nominal ±3 V input) by a fixed gain of 100, so an engineer can drive a piezo stack actuator without distortion and reach nanometre displacement resolution and repeatable positioning accuracy.
- Characterising electrostatic drive in MEMS devices — In a semiconductor R&D laboratory, measuring the pull-in voltage of a MEMS electrostatic comb-drive or thin-film structure means sweeping a bias of several hundred volts. An engineer takes a low-amplitude sweep waveform from a signal generator, amplifies it with the A600 into the required high voltage range, and records structural displacement and capacitance change at the same time — completing electrical characterisation at wafer level or after packaging without building a separate high voltage supply.
- Verifying the electro-optical characteristics of liquid crystal cells and OLED materials — In flat panel display materials research, both the switching voltage of a liquid crystal cell and the carrier injection behaviour of an OLED require precise AC or pulse signals spanning several hundred volts. The A600's broadband linear amplification (DC to several hundred kHz) lets researchers define the drive waveform on an arbitrary waveform generator, apply it to the test sample through the A600, and record the electro-optical response alongside an optical measurement system — shortening material screening and process parameter tuning considerably.
