Economy calibration kits
Include the open circuit, short circuit, and fixed
termination standards but not sliding terminations
or gauges. Gauges can be ordered separately.
Waveguide calibration kits
Contain two coax-to-waveguide adapters with
precision flanges, a flush short circuit, a precision
waveguide line section, and either sliding or fixed
terminations. They support calibration based on
TRL/TRL*, offset load, or short/offset-short/load/
thru methods.
Agilent 85060 series electronic calibration system
Electronic calibration (ECal) replaces the usual
calibration kit standards with a solid-state calibra-
tion module. The module is controlled by analyzer
firmware via an interface kit to present different
impedances to the test ports. A full two-port cali-
bration can be done with a single connection in
just a few minutes, with less chance for error and
less wear on connectors. An ECal system requires
an 85097A interface kit and an 85060 series cali-
bration module. The 85097A includes software for
Windows® 95, 98 and NT® 4.0 systems, and is com-
patible with the 8720C/D/E families. A PC is not
needed when using the ECal system with an
8720D/E family analyzer.
Verification kits
Measuring known devices, other than the stan-
dards used in calibration, is an easy way to verify
the correct operation of an 8720E family network
analyzer system. Agilent offers the following verifi-
cation kits, which contain precision devices with
data traceable to NIST, to verify the analyzer’s
error-corrected measurement performance:
• 85051B 7-mm verification kit; 0.045 to 18 GHz
• 85055A type-N verification kit; 0.045 to 18 GHz
• 85053B 3.5-mm verification kit; 0.045 to 26.5 GHz
• 85057B 2.4-mm verification kit; 0.045 to 50 GHz
Test-port return cables
Test-port cables are available in the 7-mm, 3.5-mm,
type-N, and 2.4-mm connectors types. All cables
connect directly to the special ruggedized test port
of the network analyzer test port (NMD connector).
Agilent offers the following cable choices:
• Semi-rigid and flexible single cables
• Semi-rigid and flexible cable sets
A single long cable with an appropriate test port
adapter is best for applications where the test
device requires a connection next to the test port
for mechanical rigidity. A set of cables offers the
flexibility required to position the test devices
away from the test set.
Semi-rigid cables offer excellent performance and
are suitable for applications where the connectors
of the test device are “in-line” or parallel. Flexible
cables are ideal for manufacturing environments,
since they are more rugged and have a tighter
bending radius than semi-rigid cables. Semi-rigid
cables are warranted for 90 days; flexible cables
are warranted for 1 year.
