Keysight 8970B noise figure tester unlocks the mysterious veil of noise figure measurement, making measurement easier, more accurate and repeatable. And it can be used with 346 or 347 series noise sources. With low instrument uncertainty and automatic second stage correction, the 8970B can generate accurate noise figure readings even for low gain devices. The instrument provides a special measurement mode for mixer measurement, and can control the external local oscilloscope and 8971C noise figure testing device.

• Simultaneous measurement of noise figure and gain

• Simple qualification of amplifiers and frequency conversion equipment
