Easy Setup…Test…and Maintenance

Hardware platform

Connectors

The M9168C/E comes with 3.5 mm (f) (SMA compatible)/2.4 mm

(f) high quality RF coaxial connectors for 50 Ω.

Compliance

The M9168C/E is PXI compliant, using either a PXI-H, PXI-1

or cPCI slot. Designed to benefit from fast data interfaces, the

M9168C/E can be integrated with other test and automation

format offers high performance in a small, rugged package, and

it’s an ideal platform for many automated test systems. A wide

array of complementary PXI products are currently available

and include multimeters, waveform generators, local oscillators,

digitizers, and switch multiplexers.

Software platform

Drivers

Keysight‘s M9168C/E comes complete with software drivers

for Windows XP, Windows Vista, Windows 7, and LabVIEW.

Also included are application code examples for LabVIEW,

LabWindows/CVI, Visual Studio, C, C++, MATLAB.

Soft Front Panel

The M9168C/E graphical user interface guides developers

through the module setup process. Users can quickly configure

the module parameters. The interfaces are implemented using

the IVI standard supporting both IVI-COM and IVI-C.

Soft front panel of M9168C/E provides an intuitive approach for

program simulation and troubleshooting. The soft front panel

comes in Uncorrected and Corrected instance.

Uncorrected — User sees the nominal value of the attenuation in

this instance, regardless of operating frequency.

Corrected — Calibration data is burnt in the module EEPROM

at factory and is unique to each step attenuator module. The

corrected data is the attenuation value by frequency. User could

read the actual attenuation value that changes with frequency,

and with accuracy up to 2 decimal points.
