USBPGF-S1 Programmable Gain Instrumentation Amplifier with Variable Frequency Low Pass Filter

Software-Controlled 8-Pole Low Pass Filter with Variable Gain Amplifier

The USBPGF-S1 is a fully programmable single-channel instrumentation amplifier combined with an 8-pole low pass filter. All parameters — gain, cutoff frequency, and coupling — are controlled via USB.

Key Features

• Differential or single-ended input with ±40V protection
• Software programmable gain from 1 to 10,000
• Programmable corner frequency from 0.1 Hz to 200 kHz (model dependent)
• Available filter responses: Butterworth, Bessel, Linear Phase, Cauer/Elliptic
• Software selectable DC or AC coupling
• Non-volatile memory retains settings after power cycle for "Turn Key" operation
• Compatible with any 12, 16, or 24-bit A/D converter
• Includes Windows control software and SDK with API examples

Ideal for vibration analysis, precision sensor conditioning, and any application requiring clean anti-aliased signals with programmable gain.

Multi-channel Convenience

For multi-channel convenience populate the USBDR-8 USB and power distribution rack with USBPGF-S1 modules. The USBDR-8 can hold up to 8 modules and can be daisy chained to create very large channel counts with one host computer.

Connection to the Data Acquisition System

All I/O connections from the USBPGF-S1 are made via two BNC connectors or from the supplied removable screw terminal connectors.
