Factory integration of the N5250C system integrates the E8361C
with Option H11 and the N5260A millimeter-wave controller with
test heads. On-site installation is included, and the entire system
carries a full one-year, on-site warranty (where available).
Option Descriptions
□ Millimeter-wave modules with bias-tees (N5250C Option 017)
Adds 67 GHz bias-tees to the combiner assembly between the
input to the combiner and the 67 GHz coupler. The bias-tees have
tri-axial connectors for force, sense, and ground. Positioning the
bias-tees close to the DUT greatly improves stability for on-wafer
and in-fixture devices. The bias-tees added for this option have a
voltage rating of 40 volts and a maximum of 0.5 amps.
□ Millimeter-wave modules with bias-tees and port 2
attenuator (N5250C Option 018)
Adds 67 GHz bias-tees to the combiner assembly between the
input to the combiner and the 67 GHz coupler. The bias-tees have
tri-axial connectors for force, sense, and ground. Positioning the
bias-tees close to the DUT greatly improves stability for on-wafer
and in-fixture devices. The bias-tees added for this option
have a voltage rating of 40 volts and a maximum of 0.5 amps
Additionally, Option 018 adds a 25 dB micrometer attenuator to
the port 2 test head.
Banded waveguide solution
In order to assemble a banded waveguide solution, the following
components are needed:
• Microwave PNA network analyzer (E8361C or E8362/3/4C)
with the following options:
• IF access - Option H11
• Configurable test set - Option 014
• Extended power range and bias-tees - Option UNL
• Frequency-offset mode - Option 080
• Reference channel switch - Option 081
• Millimeter-wave test set controller (N5260A)
with no options
• A set of waveguide modules:
• N5256AW15, 50 to 75 GHz
• N5256AW12, 60 to 90 GHz
• N5256AW10, 75 to 110 GHz
• N5256AW08, 90 to 140 GHz
• N5256AW06, 110 to 170 GHz
• N5256AW05, 140 to 220 GHz
• N5256AW03, 220 to 325 GHz
NOTE: To significantly improve system dynamic range above 220 GHz,
Agilent strongly recommends adding two external synthesizers
such as Agilent’s PSG Series signal generators; one for the RF sig-
nal, and one for the LO signal.

On-wafer applications
For on-wafer applications, Cascade Microtech
3
provides complete
probing systems using the N5250C. These include both new prob-
ing systems and upgrades to existing Cascade Microtech products.
Cascade can also provide on-wafer verification and probing system
training. Once the N5250C system is verified in coax, Cascade
Microtech will verify the system through its
wafer probes.
