The ME7808A Broadband Vector Network Analyzer (VNA) is a high
performance measurement solution that covers 40 MHz to 110 GHz
in a single fast sweep. In contrast to the millimeter wave Vector
Network Analyzer, the ME7808A is built on the advanced technology
of the Lightning 65 GHz VNA, and extends its advanced features and
intuitive user interface to 110 GHz.
The configuration for the Broadband VNA consists of:
• Lightning 65 GHz VNA
• Millimeter-Wave Modules (Extended W Band, 65 GHz to 110 GHz)
• Broadband Test Set
• Frequency Sources
• Multiplexing Couplers
• Equipment Console with table

Measurement Speed and Accuracy
The Broadband VNA, based on our popular Lightning 37397C platform,
offers the fastest measurement speed available. Measurement
speed of approximately 1.5 seconds for a 101 point sweep means
faster characterization of your millimeter wave and broad frequency
devices. The ME7808A also offers full auto-reversing, 12-term, error-
corrected S-parameter measurements with advanced calibration
techniques – such as Short-Open-Load-Thru (SOLT), Line-Reflect-
Line (LRL), and Line-Reflect-Match (LRM) – ensuring maximum ac-
curacy in your on-wafer measurements. For waveguide measure-
ments, the ME7808A system supports all of the above methods as
well as the offset short calibration technique. The 8.5 inch, color liq-
uid crystal display (LCD) allows users to easily view the data traces
for all four S-parameters while simultaneously displaying limit lines
and trace memory functions. The built-in 3.5 inch MS-DOS ® com-
patible floppy disk drive and internal hard disk drive simplify the pro-
cedure of storing and recalling calibrations, front panel setups, and
measurement data. The versatility of the Lightning platform allows
data to be gathered using the *.s2p, *.txt, *.dat, *.bmp, *.hgl, and the
*.wmf file format so data can be easily loaded into both circuit simu-
lation and graphics programs.
• Single Pair of Coaxial Test Ports
The ME7808A Broadband VNA combines the 40 MHz to 65 GHz
output from the VNA and the 65 GHz to 110 GHz output from the
mmW modules using a unique multiplexing coupler design. The ef-
fective system test ports for broadband frequency coverage are two
W1 (1.0 mm) coax connectors. The Anritsu W1 connector is com-
patible with the IEEE standard 1.0 mm connector. This design pro-
vides a DC path that permits bias injection from the VNA front panel
bias inputs directly to the W1 coax test ports.
• Three Systems in One
The Broadband VNA system provides maximum versatility and can
be used in any of the following configurations:
1) as a broadband VNA (40 MHz to 110 GHz) with W1 (1.0 mm) con-
nector coaxial interface
2) as a stand-alone 65 GHz VNA with V-connector coaxial interface
3) as a millimeter-wave VNA (65 GHz to 110 GHz) with a WR-10
waveguide connector interface. Additional discrete mmW bands are
easily supported by substituting other available mmW modules into
the system.
This flexibility in measurement interface allows you to tailor the
Broadband VNA to your exact measurement needs. When operating
either the 65 GHz or mmW systems independently, higher output
power and increased dynamic range are achievable. Wafer probe
tips can be connected to any of the three interfaces to make on-wafer
measurements.
• Complete Measurement Solutions
The Anritsu Broadband VNA is compatible with leading probe sta-
tions and probe tips for making on-wafer measurements. On-wafer
calibration software such as SussCal from Karl Suss and WinCal
from Cascade Microtech have built in drivers for the Anritsu VNA’s
and therefore can be used with the ME7808A. In addition, Anritsu
also offers a complete list of accessories including coaxial calibration
kits, waveguide calibration kits, on-wafer calibration substrates, W1
(1mm) coaxial and waveguide to coaxial adapters.
