Introduction and Installation
Introduction to the Multiport Test Set
Introduction to the Multiport Test Set
• The 87050E is a 50-ohm multiport test set that is available with 4, 8, or 12 test
ports.
• The 87075C is a 75-ohm multiport test set that is available with 6 or 12 test
ports.
A Complete Multiport Test System
87050E and 87075C multiport test sets are designed to work with E5061A (1.5
GHz) and E5062A (3 GHz) RF network analyzers to provide complete
measurement systems for 50 ohm and 75 oh m multipor t devic es. These tes t systems
offer fast measurement speed, high accuracy, and productivity features that will
maximize your production throughput. They feature:
• specified performance to 1.3 GHz (87075C) or 2.2 GHz (87050E - with typical
performance to 3 GHz)
• solid-state switches for fast, repeatable, and reliable switching between
measurement paths
Fully Characterize Your Devices with a Single Connection
A single connection between the multiport test set and each port of the DUT allows
complete testing of all transmission paths and port reflection characteristics. Agilent
multiport test systems eliminate time-consuming reconnections to the DUT, keeping
your production costs down and your volumes up. By reducing the number of RF
connections, you also:
• lower the risk of misconnections
• reduce operator fatigue
• minimize wear on cables, fixtures, connectors, and the DUT
2 Chapter 1
Introduction and Installation
Introduction to the Multiport Test Set
Improve Your Competitiveness with a Fully Specified Test System
A multiport test set coupled with an E5061A/E5062A network analyzer offers fully
specified performance at the actual test po rts, wheth er y ou measure in a fixture or at
the end of test cables. Specified performance means you can:
• get the same results no matter which test station you use to measure your DUT
• correlate test data from many DUTs across multiple test systems
• reduce measurement uncertainty to tighten your product specifications
• increase customer confidence in your products
Eliminate Redundant Connection of Calibration Standards with Test Set Cal
Calibrating a multiport test set using two-port error correction and a traditional
network analyzer requires a unique instrument state for each measurement path,
forcing many redundant connections of calibration standards. As the number of
ports increases, so does the number of connections required to calibrate all possible
measurement paths. Full calibration of the multiport test system is quick and simple
when performing a Test Set Cal:
• connect short, open, and load standards only once to each measurement port
• minimize the number of through standards required during calibration
Chapter 1 3
Introduction and Installation
Introduction to the Multiport Test Set
Reduce the Effects of Test-System Drift with SelfCal
SelfCal is an internally automated calibration technique that uses solid - state
switches to measure calibration standards located inside the test set. SelfCal
executes automatically in just a few seconds (at an interval you define), so the
impact to your test process is minimal. Use SelfCal to:
• re-calibrate your multiport test system, returning it to the same measurement
accuracy achieved immediately after performing a Test Set Cal
• reduce the effects of test-system drift, improving overall measurement accuracy
between Test Set Cals
Since SelfCal does not correct for drift associated with interconnect elements
between the test set and your DUT, it is essential to use high-quality test cables,
adapters, and fixtures to ensure the best measurement accuracy.
Decrease Calibration Times and Increase Production Throughput
With SelfCal, a Test Set Cal needs to be performed about once per month, if within
the specified temperature range. This is unlike other test systems that typically
require calibration once or twice a day. Using Test Set Cal and SelfCal, you can:
• easily reduce your overall calibration times by a factor of twenty or more
• increase the amount of time a test station can be used for measuring
devices—typically, by three days per month.
Improve Measurement Accuracy with Two-Port Calibration
When using a multiport test set with an E5061A/E5062A with the option 27 5
S-parameter test set, Test Set Cal and SelfCal support full two-port calibrations.
Two-port error correction greatly improves the effective load match of the test
system, providing excellent measurement accuracy.

Preventive Maintenance
Preventive maintenance consists of checking the front panel conn ectors. This should
be done at least every six months — more often if the test set is used daily on a
production line or in a harsh environment.
Vis ually inspect the fron t panel conn ectors. The most important connecto rs are those
to which the DUT is connected. All connectors should be clean and the center pins
centered. The fingers of female connectors should be unbroken and uniform in
appearance. If you are unsure whether the connectors are good, gauge the
connectors to confirm that their dimensions are correct.
CAUTION 87050E multiport test set only:
Connecting 75 ohm cables to the front panel 50ohm connectors of the analyzer
or test set usually results in intermittent or no electrical connections.
CAUTION 87075C multiport test set only:
Never connect 50 ohm cables to the front panel 75 ohm connectors of the analyzer
or test set. Otherwise, irreparable connector damage will occur.
