Introduction
Electronic calibration (ECal) is
a precision, single-connection,
one-, two-, three-, or four-port
calibration technique for your
vector network analyzer. ECal
modules use fully traceable and
verifiable electronic impedance
standards. The modules are
state-of-the-art, solid-state
devices with programmable and
highly repeatable impedance
states. ECal modules are transfer
standards that provide consis-
tent calibrations and eliminate
operator errors while bringing
convenience and simplicity to
your calibration routine.
Consistent calibrations provide
consistent measurements.
ECal replaces the traditional
calibration technique, which
uses mechanical standards. With
mechanical standards you are
required to make numerous
connections to the test ports
for a single calibration. These
traditional calibrations require
intensive operator interaction,
which is prone to error. With
ECal, a full one- to four-port
calibration can be accomplished
with a single connection to the
ECal module and minimal
operator interaction. This results
in faster and more repeatable
calibrations.
Mixed-connector options are
available for the 85092C,
85093C, 85098C, N4431B and
N4432A. The available connectors
are Type-N 50 ohms, 3.5mm, and
7-16.
Accurate transfer
standards
The ECal modules are transfer
standards capable of transferring
the factory calibration accuracy to
your network analyzer. They are
characterized by Agilent using a
precision calibration technique
(similar in accuracy to TRL)
that is traceable to the National
Institute of Standards and
Technology (NIST). Each calibration
module’s unique S-parameter data
is stored in the module’s memory.
During calibration, ECal uses this
data to calculate the error terms
for your network analyzer. All
measurements on either insertable
or non-insertable devices are
traceable to NIST.
Faster calibration
with a single
connection
Unlike the traditional mechanical
technique, ECal only requires
one connection to perform a
full one- to four-port calibration
from the calibration module to
the test ports.
By reducing the number of
connections required for a
calibration, you can
• calibrate faster, so you save
time and make measurements
sooner
• reduce the chance of operator
error, for greater confidence in
your calibrations
• reduce the wear on connectors,
for lower repair costs on both
the test port connectors and
calibration standards
Network analyzer
compatibility
The 85090 family of RF ECal
modules provides calibration
across the frequency range of the
ENA and 8753 series of network
analyzers. The N4690 family of
microwave ECal modules pro-
vides calibrations through 67 GHz
for PNA-L and PNA network
analyzers. The N4430 family of
four-port modules provide
calibration for the ENA, PNA,
and 4-port PNA-L, and any
multiport solutions.
