# Keysight B2201A 14ch Low Leakage Switch Mainframe (Pre-Owned) # Keysight B2201A 14ch Low Leakage Switch Mainframe (Pre-Owned) ## Key Features At A Glance - Switches DC current, DC voltage, capacitance, and LCR meter measurements through a single low-leakage matrix - Eight triaxial I-V input ports (or four Kelvin triaxial), plus six BNC AUX ports including two dedicated CV ports - Up to 48 triaxial output channels: 12 per switch module, four modules maximum per mainframe - GP-IB interface control with auto ground, self-test, relay function test, and relay cleaning functions - Front-panel LED matrix status display with light-pen connection setup - Includes a VXI Plug&Play driver with a capacitance compensation routine The Keysight B2200A fA Leakage Switch Mainframe and B2201A 14ch Low Leakage Switch Mainframe are matrix switching systems that route DC current, DC voltage, capacitance, and LCR meter signals between measurement instruments and the device under test. Connection status is set and monitored on the front panel through a configured LED matrix display, with channel connections established using a light pen. Both mainframes are controlled through a GP-IB interface and provide auto ground, self-test, relay function test, and relay cleaning functions. A switch matrix consolidates multiple instruments and test points into one automated signal-routing system. On the input side, each mainframe provides eight triaxial I-V ports (or four Kelvin triaxial ports) for low-leakage routing, along with six BNC AUX ports that include two dedicated CV ports, and all input ports can be used concurrently. Output channels are added through switch modules: each module carries 12 triaxial ports, and a frame accepts up to four modules for a maximum of 48 output channels. ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house by our technicians, while new units ship factory-sealed exactly as received. Holding our own stock lets us match the right instrument and condition to your application and ship it quickly. ## Brand Heritage Keysight Technologies traces its test-and-measurement heritage to Hewlett-Packard, whose instrument business was spun off as Agilent Technologies in 1999 and then established as the standalone Keysight Technologies in 2014. ## Compare Other Models in This Series The B2200A/B2201A family pairs a switch mainframe with a matching switch module: the B2200A fA Leakage Switch Mainframe uses the B2210A module, and the B2201A 14ch Low Leakage Switch Mainframe uses the B2211A module. Both mainframes share the same core architecture — eight triaxial I-V input ports (or four Kelvin triaxial), six BNC AUX ports with two dedicated CV ports, up to 48 triaxial output channels across four modules, GP-IB control, and front-panel light-pen setup with an LED matrix display. The two configurations differ in leakage and noise performance and in certain channel characteristics. Because each mainframe supports only its corresponding module and mixed configuration is not supported, the mainframe and module are selected together based on the required leakage-performance level. Each model below is its own dedicated product page with condition-matched pricing for the pre-owned configuration you need. Select the mainframe and its matching switch module for your leakage-performance requirements, and review each model's full specifications on its individual page before ordering. The B2200A, used with the B2210A fA leakage switch module, represents the family's lowest-leakage configuration: supplemental characteristics list offset current of 10 fA and IM noise of 0.6 fA RMS at the I-V port, with channel isolation resistance up to 1x10^14 Ω on the I-V port and channel crosstalk capacitance below 1 pF/ch. Per the supplemental characteristics, the B2200A/B2210A configuration lists offset current of 10 fA, IM noise of 0.6 fA RMS, I-V channel isolation resistance of 1x10^14 Ω, I-V channel crosstalk capacitance below 1 pF/ch, and settling time of 2.0 seconds at 50 fA. The B2201A/B2211A configuration lists offset current of 100 fA, IM noise of 5 fA RMS, I-V channel isolation resistance of 5x10^13 Ω, I-V channel crosstalk capacitance below 0.5 pF/ch, and settling time of 2.0 seconds at 300 fA. Shared module ratings include maximum current of 1.0 A (I-V) and 0.5 A (AUX), maximum voltage of 200 V I-V to common and 300 V I-V to other channels, 30 MHz AUX bandwidth, and guard capacitance below 145 pF. Module weight differs at approximately 4.5 kg for the B2210A and 3.5 kg for the B2211A. See the comparison table that follows for the per-model values.
