Electronic calibration
Electronic calibration (ECal) is a precision, single connec-
tion, one- or two-port calibration technique that uses fully
traceable and verifiable electronic impedance standards.
ECal replaces the traditional calibration technique that
uses mechanical standards. ECal requires fewer connec-
tions. It removes the intensive operator interaction, which
is prone to errors. A full two-port calibration can be
accomplished with a single connection of the ECal
module and minimal operator interaction. This results
in a faster and more repeatable calibration. Calibrations
for non-insertable devices are equally convenient and
straight forward.
An 85097A PC interface module with control software
must be ordered to drive all ECal modules. The
85097A requires a customer-supplied PC meeting
the following minimum requirements:
• Windows 95 ® , Windows NT 4.0 ® or later operating
system
• 486 or later CPU
• 32 MB of RAM
• 10 MB available hard-disk space
• one of the following GPIB interface cards:
82340A/B, 82341C/D, National AT-GPIB/TNT,
National AT-GPIB/TNT (plug&play) or National
PCI-GPIB
ECal modules are controlled manually or automatically
via the 85097A PC interface module with control soft-
ware. The 85097A consists of a PC interface module, con-
trol software and a power supply.
The Agilent 85090 family of RF ECal modules provides
calibration across the complete frequency range of the
8753C/D/E vector network analyzers. The 85060 family of
microwave ECal modules provides calibrations through
26.5 GHz for the 8510B/C and 8719/20/22C/D vector net-
work analyzers.

1. For ECal modules with sexed (m-f) connectors, the standard modules have one female and one male connector.
2. RF ECal modules are specified to operate from 300 kHz to 6 GHz, with typical performance down to 30 kHz.
A. 85060 series modules cover a frequency range of 1 GHz to either 18 or 26.5 GHz. The upper frequency is limited by
the connector cutoff frequency. Each module is supplied with a torque wrench and foam-padded wood storage box.
B. 85090 series modules cover a frequency range of 30 kHz to 6 GHz. Each module is supplied with a torque wrench and
foam-padded wood storage box.
