optimized for High Speed
Production Test
Keithley’s instruments can be configured into
sophisticated test systems that dramatically
reduce device test times and lower capital costs
compared to traditional rack-and-stack test sys-
tems. They are designed for demanding system
applications requiring ultra-fast test times and
accurate, repeatable measurements. Test script
control and intra-instrument triggering work
in cooperation to minimize bus traffic from
the PC controller. Keithley’s RF test systems
have reduced test times by up to 70% in RFIC
production applications. Using smart instru-
ments instead of test modules also reduces the
engineering time for system test integration.
This lowers schedule risk and provides greater
flexibility to reconfigure the system quickly
to transition new devices and equipment into
production.
MIMo Test Systems
Every Model 2820 is MIMO-ready to meet the
requirements of the 802.11n WiFi and 802.16e
mobile-WiMAX Wave 2 multi-input, multi-output
communications standards. Standard Model
2820 instruments can be configured into a
Ч2, Ч3, or ×4 multi-input test system with the
addition of a Model 2895 MIMO Synchronization
Unit. The synchronization unit distributes a
common LO (local oscillator), common clock,
and precise trigger to all the signal analyzers
connected in the system. This results in a high
performance multi-input signal analysis test
system with precise synchronization and low
jitter between each of the signal analyzer inputs
of both the RF carriers and waveform
signal samplers.
Full 4×4 MIMO testing is possible when this
configuration is combined with the Model
2920-based multi-output signal generator test

Through the use of test script control and intra-instrument triggering, this RF power amplifier
test system based on the Model 2820 and the Model 2920 can reduce test times by up to 70%.
system. Imagine configuring a MIMO test system
initially as a 2×2 system, then later upgrading
it to 3×3 or to 4×4 by adding more Model 2820
and 2920 units. Moreover, the instruments need
not be dedicated to a MIMO system. They can be
configured for use either in a MIMO system or
as stand-alone SISO (single input, single output)
instruments by selecting the configuration in firm-
ware and changing a few cables on the rear panel.
