Overview
The Pendulum Instruments F30PV is a broadband single-channel high voltage linear amplifier with a frequency response covering DC to 5 MHz, a bipolar ±35 V output voltage, up to 1.5 A of continuous output current and a slew rate of 500 V/µs, meeting the most demanding high-speed drive requirements. Gain adjusts continuously from 0 to 10, the standard input impedance is 500 Ω (in parallel with 30 pF) and the input voltage range is ±3.5 V, so it connects straight to a function generator or arbitrary waveform generator with no matching circuit. An output impedance below 1 Ω makes the voltage at the load follow the setting accurately for high-fidelity waveform reproduction. The F30PV has an input protection network that limits the signal amplitude to ±3.5 V, plus a 15 mA microfuse and an output short-circuit protection circuit, so an accidental short is withstood safely. The capacitive load limit is 1 nF (corresponding to the 500 V/µs slew rate), which suits piezo actuators, MEMS devices, OLED and liquid crystal displays. At 257 × 102 × 262 mm and 4 kg, running from a 100 V, 110 V or 220 V, 50/60 Hz supply, it is an ideal high-speed linear amplification solution for the R&D laboratory and the production line.
Key features
- High-speed broadband amplification — Frequency response covers DC to 5 MHz with a slew rate of up to 500 V/µs, reproducing high-frequency transient waveforms precisely for high-speed drive and control applications.
- Continuously variable gain, 0 to 10 — The gain knob adjusts steplessly between 0 and 10, and with the ±35 V bipolar output it adapts flexibly to signal sources and loads of every kind.
- High voltage, high current output — A maximum output voltage of ±35 V and 1.5 A of continuous output current give it ample capability to drive piezo actuators, MEMS devices and capacitive loads.
- Layered protection design — An input protection network limits the signal to ±3.5 V and a 15 mA microfuse is fitted; the output has a short-circuit protection circuit, keeping both the instrument and the device under test safe.
- Low output impedance — An output impedance below 1 Ω (in the linear region) makes the voltage at the load follow the input setting very faithfully, reducing drive error.
- Applications across many fields — Suited to the development and production test of piezo actuators, MEMS devices, OLED panels and liquid crystal modules, and it connects directly to a function generator or arbitrary waveform generator.
Typical applications
- Precision piezo actuator drive and dynamic characterisation — An engineer feeds the low voltage signal from an arbitrary waveform generator (AWG, within ±3.5 V) into the F30PV and uses the variable gain (0–10×) to amplify it to the voltage swing a piezo stack actuator needs (up to ±35 V), relying on the high 500 V/µs slew rate to keep the waveform undistorted in kHz-band frequency response experiments — widely used in the calibration of nanopositioning stages and the development of active vibration suppression systems.
- Electrostatic drive and functional test of MEMS devices — MEMS devices such as electrostatic micromirrors and microresonators need broadband high voltage excitation from DC to several MHz during functional verification. The F30PV's DC to 5 MHz linear bandwidth and low output impedance (<1 Ω) reproduce the waveform faithfully while charging and discharging the device's small capacitive load, so a development team can run a frequency sweep, locate resonances and carry out voltage stress testing on one instrument, shortening the MEMS sample verification cycle.
- Evaluating the electrical characteristics of OLED and liquid crystal devices — A display materials laboratory assessing the electro-optical response of a new OLED emissive layer or a liquid crystal cell needs repeatable, highly linear bipolar drive waveforms. A researcher supplies a precise waveform from a signal generator and uses the F30PV's adjustable gain to switch between drive voltage levels quickly, capturing current and luminance response with an oscilloscope and extracting key parameters such as threshold voltage, hysteresis curve and switching time accurately.
