Introduction

 

Features and description

  • Exceptional reliability, long life (5,000,000 cycles minimum)
  • Excellent repeatability
  • Compact – Easy GPIB implementation for ATE applications
  • Single-pole, multiple-throw models available:

    • three-throw (8766K)
    • four-throw (8767K)
    • five-throw (8768K)
    • six-throw (8769K)

This Keysight Technologies, Inc. family of single-pole, multiple-throw switches utilizes the same proven technology as the well known Keysight 849X family of step attenuators. These products offer the same rugged reliability, excellent repeatability (typically 0.01 dB to 18 GHz and 0.05 dB to 26.5 GHz), long life (greater than 5 million switching cycles), compactness, and broadband performance as the 849X family. Each product consists of 2 to 5 solenoid driven switching sections connected in series. The solenoid armatures are held in place with permanent magnets able to withstand shocks over 10 g’s. 

 

The sections switch within 20 milliseconds, including contact settling time, which is of importance for automatic test applications. The switches include self-interrupting contacts which minimize power consumption and simplify the driver circuit design (figure 1). Each model is available with a wide range of solenoid voltage choices (24 volts, standard, or optionally 5 or 15 volts) to match your product or system’s requirements.
