What it is

A low leakage switch mainframe is a programmable switching system used in semiconductor parametric test to route signals between measurement instruments and devices under test. The Keysight E 5250 A is a low leakage switch mainframe that expands a single measurement station to an automated measurement system.^[2]^[3]

How it works

The E 5250 A switches DC current, DC voltage, capacitance, and pulse signals with DC instruments and LCR meters. The mainframe controls switching through a built-in GPIB interface. Plug-in modules can be configured either as a cross-point matrix for general parametric measurements or as a multiplexer for long-term reliability measurements.^[2]^[3]

Switch modules plug into four slots that accept 30 mm height switch cards. The mainframe performs a self-test using the optional relay function test adapter (Option 301). Typical performance includes an offset current of less than 0.1 pA on the low leakage I-V port and a relay contact life greater than 10^8 operations in dry switching mode.^[2]^[3]
