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
8712ET/ES (1.3 GHz) and 8714ET/ES (3 GHz) RF network analyzers to
provide complete measurement systems for 50 ohm and 75 ohm
multiport devices. These test 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

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 8712E series network analyzer
offers fully specified performance at the actual test ports, whether you
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

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 8712ES or 8714ES S-parameter
network analyzer, 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.

Step 3. Connect the Test Set to the Analyzer
For using your system on a bench, configure and connect the two
instruments as shown in Figure 1-4. Use the parallel cable that was
shipped with the multiport test set to connect to the analyzer as shown.
If you will be installing your system in a rack, read “Installing the
System in a Rack,” next in this section, before connecting the test set to
the analyzer.
Figure 1-4 System Configuration
1-14 Chapter 1
Introduction and Installation
Installation
Installing the System in a Rack
Use only the recommended rack mount kit for the network analyzer
(Option 1CM when ordered with the analyzer, or part number
08712-60036 when ordered separately): it needs side support rails. Do
not attempt to mount the analyzer by the front panel (handles) only. The
recommended rack mount kit allows you to mount the analyzer with or
without handles.
The rack mount kit for the test set is Option 1CM when ordered with the
test set, or part number 5063-9214 when ordered separately.
NOTE There are special semi-rigid cables that should be used to connect the
analyzer’s test ports to the test set’s REFLECTION and
TRANSMISSION ports when used in a rack (or a bench configuration
where the analyzer’s bottom feet have been removed). These cables were
shipped with your analyzer if you ordered Option 1CM. If you order the
rack mount kit separately, you will need to order these special cables
separately also. See Table 1-1 on page 1-11 for part numbers.
To install your system in an 85043D rack, follow the instructions in the
rack manual.
CAUTION When installing your system in other racks, improper installation may
cause shock hazards, overheating, dust contamination, and inferior
system performance. For support details and information about
installation and warranty, call Agilent Technologies. Refer to page 35 for
the nearest office.
CAUTION When installing the system in a cabinet, the convection into and out of
the system must not be restricted. The ambient temperature (outside the
cabinet) must be less than the maximum operating temperature of the
system by 4 °C for every 100 watts dissipated in the cabinet. If the total
power dissipated in the cabinet is greater than 800 watts, then forced
convection must be used.

Step 4. Satisfy Electrical and Environmental Requirements
NOTE Refer to your network analyzer’s User’s Guide for information on
electrical and environmental requirements for your network analyzer.
1. The line power module on your multiport test set has an autoranging
input. It is designed to be used with an ac power source with a
nominal voltage of either 115 V or 230 V.
2. Ensure the available ac power source meets the following
requirements:
Nominal Range
Frequency: 50/60 Hz 47–63 Hz
Line Voltage: 100/115 V or 230/240 V 90–264 V
Power 45 W max
CAUTION This product has an autoranging line-voltage input. Be sure the supply
voltage is within the specified range.
If the ac line voltage does not fall within these ranges, an
autotransformer that provides third-wire continuity to earth ground
should be used.
3. Ensure the operating environment meets the following requirements
for safety:
• indoor use
• altitude up to 15,000 feet (4,572 meters)
• temperature 0 °C to 55 °C
• maximum relative humidity 80% for temperatures up to 31 °C
decreasing linearly to 50% relative humidity at 40 °C
• use only in INSTALLATION CATEGORY II, and POLLUTION
DEGREE 2, per IEC 1010 and 664 respectively
