Keysight Technologies N5256BW15

The N5256BW is a frequency extender module supplied by OML to perform measurements with an N522xB PNA or N524xB PNA-X vector network analyzer in 60 to 90 GHz (E-band). It can be used with a PNA/PNA-X and an N5261/62/92A test set controller or directly connected with a 4-port PNA/PNA-X for direct control configuration. This measurement configuration allows you to run most of the PNA software applications in E-band.

The millimeter-wave modules are designed for use with the N5260/61/62A Millimeter-wave Module Controllers for banded vector network analyzer systems. Refer to the N5250C or N5261/62A Users Guides (N5260-90001 or N5262-90001) for system connections, operation and functional check. 

The N5256A/B “T/R” Millimeter-wave Module contains an RF source multiplier, dual directional coupler, reference downconverter and a test downconverter. The T/R Millimeter-wave Module is usually the primary module of a millimeter-wave VNA system. A single T/R module allows the measurement of S11 reflection coefficient only.

The single and dual channel receiver modules are used for antenna applications or for 1-port single path S-parameter measurements.

VNA modules enable engineers to conduct mm-wave S-parameters. The DUT interface is the standard waveguide flange that complies with MIL-DTL-3922/67D. Organized by waveguide bands, VNA modules are available from 50 GHz to 0.5 THz.

The N5256BW15 will expand your existing VNA capabilities so you can conduct millimeter wave S-parameter measurements from 50 to 75 GHz.

Modules are available in a variety of S-parameter configurations: T/R, T and/or S. They also offer various options including variable attenuation, low power, intermodulation distortion measurements (IMD) and extended frequency bands.

Note:

¹ Waveguide models maybe ordered with;

Option 001 (Adjustable RF Attenuator)

Option 002 (15 dB Gain, RF and LO Internal Amplifiers)

Option 003 (Option 001 and Option 002)

Option 004 (IF amp bypass jumpers).

Notes:

• A power supply is included with each module ordered.
• The modules with the RF/LO amplifiers are for antenna applications that include a cable loss of 15 dBm to the module from the port of the test set controller being used. Do not connect these directly to the test set controller port with the standard 48 inch cable, usea 15 dB pad if needed.

¹ BW15/12 and AW15/12 models cannot be mixed in a system. (BW and AW have different LO multipliers.)

² BX12 and AX12 model cannot be mixed in a system. (BX and AX have different LO multipliers.)

³ N5256AW12/15 and N5256AX12 are non-RoHS versions.

⁴ The modules with Option 003 have the +15 dBm RF/LO amplifiers. A 15 dB attenuator must be connected when the modules are connected with 1.2 m cables.

Notes:

¹ Waveguide models with Option 001 (Adjustable RF Attenuator).

² Waveguide models with Option 002 (15 dB Gain, RF and LO Internal Amplifiers).

³ Waveguide models with Option 003 (Option 001 and Option 002), or Option 004 (IF Amplifier Bypass Jumpers).
