F30PV
DC to 5 MHz variable-gain high-speed linear amplifier, bipolar ±35 V / 2 A output
Two things set the F30PV apart from the rest of the range: gain that is continuously adjustable from 0 to 10x, and DC to 5 MHz bandwidth paired with a 500 V/µs slew rate. Variable gain earns its keep during experiments, when you are not yet sure how much amplification you need or different devices under test need different amplitudes; turning a knob is faster than swapping instruments. Output is ±35 V bipolar at 2 A continuous. The voltage is modest but the current is ample and the speed is high, which suits ultrasonic transducers, piezo elements and fast excitation of low-impedance resistive loads. The manual specifies resistive and capacitive loads and rules out inductive loads.
Overview
A fixed-gain amplifier is an asset in a production setup because nobody can misadjust it. In development and experimental work, fixed gain means every amplitude change goes back to the signal source, and when the source has limited resolution a small output amplitude throws away bits. The F30PV puts amplitude control at the amplifier with its 0 to 10x continuous gain: the source stays at its best output range and the amplifier sets the final level, which gives a better signal-to-noise ratio. On speed, DC to 5 MHz and 500 V/µs are the fastest class in this product line, suited to ultrasonic excitation, fast pulse drive and experiments that need steep edges. The ±35 V output with 2 A continuous current makes it a power-oriented rather than voltage-oriented instrument; low-impedance loads such as 50 Ω resistive loads and ultrasonic transducers are its home ground, the manual specifies resistive and capacitive loads and rules out inductive loads, and the bipolar output drives in both directions. If you need both 5 MHz speed and more than 35 V of swing, say so when you request a quotation; that combination needs separate confirmation.

Features
Gain continuously adjustable 0 to 10x
Change amplitude with a knob during experiments; the source stays at its best output range for a better signal-to-noise ratio.
DC to 5 MHz
The fastest class in the series, covering ultrasonic excitation and fast pulse drive.
500 V/µs slew rate
Steep edges are not limited by the driver; pulse shape is set by the load and the source.
2 A continuous current
Built for low-impedance loads: ultrasonic transducers, piezo elements and fast excitation of 50 Ω resistive loads; never inductive loads.
±35 V bipolar
Modest voltage but drives both ways; a power application rather than high-voltage positioning.
Any signal source will do
Any generator that produces the waveform can act as the front end, no special interface needed; R&D validation and production test share one setup.
Typical applications
Piezo actuation
Precision piezo actuator drive and dynamic characterization
Engineers feed the low-voltage output of an arbitrary waveform generator (within ±3.5 V) into the F30PV and use the 0 to 10x gain to reach the swing a piezo stack needs, up to ±35 V. The 500 V/µs slew rate keeps the waveform clean during frequency-response experiments in the kHz range, in work such as nanopositioning stage calibration and active vibration suppression.
MEMS development
Electrostatic drive and functional testing of MEMS devices
MEMS devices such as electrostatic micromirrors and microresonators need wideband high-voltage excitation from DC to several MHz during functional validation. The DC to 5 MHz linear bandwidth and low output impedance (1 Ω in linear mode) of the F30PV reproduce the waveform faithfully while charging and discharging the small device capacitance, so frequency sweeps, resonance location and voltage stress tests run on one instrument and sample validation takes less time.
Display technology
Electrical characterization of OLED and liquid crystal devices
Display material labs evaluating a new OLED emissive layer or liquid crystal cell need repeatable, linear bipolar drive waveforms. Researchers generate the waveform on a signal generator, switch between drive levels quickly with the F30PV gain control, and capture current and luminance on an oscilloscope to extract threshold voltage, hysteresis and switching time.
