The Keysight R347B noise source covers a 26.5 to 40 GHz frequency range. This waveguide noise source allows you to make accurate and convenient noise figure measurements on millimeter-wave devices. The R347B provides highly precise broadband noise at the input of the system or component under test. The noise figure meter then processes the ON/OFF ratio of noise power present in the system IF, and provides an accurate reading of noise figure and gain. The R347B noise source has remarkable ENR stability over time, which allows longer recalibration cycles and more accurate noise figure measurements.

• Performance and reliability at millimeter-wave frequencies
• Excellent ENR stability over time
• Low SWR

The Keysight 346C noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 26.5 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty; reflections of test signals. Option K01 is a coaxial noise source and features coverage from 1 to 50 GHz with a 2.4 mm coaxial connector.

• Frequency range: 10 MHz to 26.5 GHz
• VSWR: < 1.35:1

• Low SWR for reducing noise figure measurement uncertainty
• Individually calibrated ENR values at specific frequencies

The Keysight 346B noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 18 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty, which are reflections of the test signals. Add special option H01 for high ENR (21 dB typical) to measure high noise figure devices, or option H42 for measuring Direct Broadcast Satellite (DBS) low noise block converters.

The Keysight 11970U waveguide mixer is a general-purpose harmonic mixer employing a dual-diode design to achieve flat frequency response and low conversion loss. These are achieved without external dc bias or tuning stubs. Manual operation and computer-controlled hardware operation are simplified because mixer bias and tuning adjustment are not required.

The 11970U extends the frequency range of the Keysight N9030A PXA high-performance signal analyzer to the U-band (40 to 60 GHz). It is also fully compatible with other Keysight spectrum analyzers including: the E4440A/46A/48A PSA (with Option AYZ), the E4407B ESA-E (with Option AYZ), the 856xEC, the 8566B (with a preamplifier), and the 7000 modular analyzer (with the 70907A/B external mixer interface module).

An external diplexer is required to connect the 11970U with the N9030A PXA (with Option EXM). The recommended diplexer can be purchased from Keysight as model number N9029BE13 or from Marki Microwave as DPXN-2-LF.
