U3047AM12 General Specifications
General Specifications
Specifications for the test set are characteristic for the system performance of the network analyzer and the
test set. Before using the network analyzer and test set a calibration is recommended for best measurement
performance. Actual performance of the system is based on the customer’s network analyzer and options
that are used with the test set. A functional certificate is only offered for the test set.
When connected to a network analyzer, this test set will degrade the performance at the test ports. The
internal switch paths reduce test port power and power to the receivers. This affects the test port power of
the network analyzer and also reduces dynamic range. The reflection tracking values measured in the “Cal
Kit Operational Check” on page 46 can be subtracted from the analyzers dynamic range to determine the
approximate performance of the system.
CAUTION The life expectancy of the following switches are 5 million cycles. When making
measurements using more than one port, single sweeps are recommended to minimize
switch cycles.
• N1811TL (x32, N1811-60019)
Power Requirements
Verify that the required ac power is available before installing the test set to the network analyzer.
• 100/120/220/240 VAC (50/60Hz)
• The instruments can operate with mains supply voltage fluctuations up to ± 10% of
the nominal voltage.
• Air conditioning equipment (or other motor–operated equipment) should not be placed on the same ac
line that powers the test set and network analyzer.
• N5247A and N5227A maximum power is 450 W.
• U3047AM12 maximum power is 350 W.
WARNING This is a Safety Class I Product (provided with a protective earthing ground incorporated
in the power cord). The mains plug shall be only be inserted in a socket outlet provided
with a protective earth contact. Any interruption of the protective conductor inside or
outside of the product is likely to make the product dangerous. Intentional interruption is
prohibited.

cabinet) must be less than the maximum operating temperature of the instrument by 4 °C
for every 100 watts dissipated in the cabinet. If the total power dissipated in the cabinet is
greater than 800 watts, forced convection must be used.
Required Conditions for Accuracy Enhanced Measurement
Accuracy–enhanced (error–corrected) measurements require the ambient temperature of the network
analyzer and test set to be maintained within ± 1 °C of the ambient temperature at calibration.
Dimensions and Space Requirements
Standard installation of the test set and network analyzer includes configuration and installation on a
customer provided lab bench or table top of adequate size and strength. For weight, dimensions and space
requirements, refer to the network analyzer documentation that is used to configure the test set.
