Control modules are our trademark product. Our driver modules let you control DC current or voltage signals, from 1 to 1000 channels, and anywhere in between. Our new current sense module lets you read out photodiodes at scale. Learn more about our line of driver modules here.
Q8iv Current & Voltage Driver Module
An 8-channel ultra precise driver module, the Q8iv has rich capabilities. This driver module, designed for silicon photonics, contains 8 fully voltage and current programmable channels. Uses a new card-edge connector system, easy to use and more robust than its predecessor. A set of fully shielded backplanes, cabling and interposer boards are available.
Features
- 8 software-defined input/output channels
- Channels configurable as voltage output, current output, ground, voltage or current sense
- Hardware voltage and current control (12 V, 24 mA)
- 16-bit output precision
- 18-bit input accuracy
Q8b Voltage Driver Module
Our economical driver module, the Q8b, contains 8 precise voltage-programmable channels. It uses our card-edge connector system which is easier to use and more robust than its predecessor. It works with our fully-shielded backplane, cable, and interposer infrastructure, and is compatible with the Q8iv and our other modules.
Features
- 8 software-defined output channels
- Channels configurable as voltage output, ground, or current sense.
- Source and sink current
- Hardware voltage and current control (12 V, 50 mA).
- 16-bit output precision
- 12-bit input accuracy
S8i Photocurrent Sense Module
On-chip photodiodes are increasingly available in germanium and indium phosphide, and can perform all kinds of functions, from active device calibration to spectroscopy. Reading out large numbers of these photodiodes though can be a challenge.
Our S8i current sense module integrates directly with our driver modules and can provide current readings across 8 channels, from 12 nA to 20 mA (about –49 dBm to +13 dBm). The S8i is ideally suited to reading high-dynamic-range photocurrents. These modules can be stacked in our standard BP8 and BP12 backplanes to provide a scalable solution to reading out many photodiodes at the same time, on- or off-chip, and they can be mixed and matched in a backplane with our other modules.
The S8i features our new milled aluminum enclosures.
Features
- 12 nA noise floor (120 pA resolution)
- 20 mA maximum reading
- 8 input channels
- bipolar inputs
