U3042AE12 General Specifications
General Specifications
Specifications for the U3042AE12 Multiport Test Set are characteristic for the System performance of the PNA and Test Set. Actual performance of the system is based on the customers PNA and options that are used with the test set. A functional certificate is only offered for the U3042AE12.
NOTE When connected to a PNA, 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 PNA and also reduces dynamic range. The reflection tracking values measured in the
Check” on page 66 can be subtracted from the analyzers dynamic range to
determine the approximate performance of the system.
Power Requirements
Verify that the required ac power is available before installing the Test Set to the PNA.

N-Port Calibration with N5230A
It is recommended that you perform an ECal characterization to minimize the connections required for multiple port calibration. The N4691B Option M0F is recommended with cable (85131F) if you are calibrating at the PNA and test set ports. Characterize the ECal module with adapters that will not be used in the measurement of the DUT.
Calibrate at the end of the test port RF cables and any adapters that are used to connect the DUT. This removes the effect on the measurement of the DUT. Failure to do this will create ripple and other measurement errors. If measurement errors occur, ensure the newest version of firmware is installed on the PNA.
Consult with Agilent Service or the firmware web page for the latest PNA, PNA-L or
PNA-X Option 551 firmware revisions and history. htt:\\na.tm.agilent.compna\firmware\firmware.htm

Read Commands
address: a integer number
Address is entered, data value will be returned. Commands should be executed with a carriage return (enter).
For example:
CONT:EXT:TEST:DATA? <address>
CONT:EXT:TEST:DATA? 0
Example: CONT:EXT:TEST:DATA? 0
This command reads the decimal equivalent of the binary data from the specified address.
The example shown above illustrates address is 0 and the returned data is 8191. Refer to

Switch Address and Data
contain the information to set the internal switch paths of the
U3042AE12 Test Set. Additional information regarding the operation and descriptions for the internal switches can be found in
“Theory of Operation” on page 83
.
The address is the first value in the Test Set I/O control or GPIB data command. The second value controls the source and receiver paths of the ports. To select a test set port configuration both switches must be set to complete the source and receiver paths. To do this you must add the decimal values together to determine the data command value,
which is the second number in the test set I/O or GPIB command. Refer Table 15
.
Table 16 and Table 17 on page 62 illustrates Port 1, 5, 9 or 13 as the configured source and
receiver paths. Refer to Table 15
to calculate other path combinations.
Example:
If Port 5 is to be the source and Port 6 is to be the receiver.
then;
Source Port 5 = address 0, decimal 2 and Receiver Port 6 = address 16, decimal 32. See
. Refer to “How to Access Interface Control Settings with N5230A” on page 29 and

U3042AE12 Electrostatic Discharge Protection
Electrostatic Discharge Protection
Protection against electrostatic discharge (ESD) is essential while removing assemblies from or connecting cables to the network analyzer. Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged. Static discharges too small to be felt can cause permanent damage. To prevent damage to the instrument:
• always have a grounded, conductive table mat (9300-0797) in front of your test equipment.
• always wear a grounded wrist strap (9300-1367) with grounding cord (9300-0980), connected to a grounded conductive table mat, having a 1 M
Ω resistor in series with it, when handling components and assemblies or when making connections.
• always wear a heel strap (9300-1126) when working in an area with a conductive floor.
If you are uncertain about the conductivity of your floor, wear a heel strap.
• always ground yourself before you clean, inspect, or make a connection to a static-sensitive device or test port. You can, for example, grasp the grounded outer shell of the test port or cable connector briefly.
• always ground the center conductor of a test cable before making a connection to the analyzer test port or other static-sensitive device. This can be done as follows:
1. Connect a short (from your calibration kit) to one end of the cable to short the center conductor to the outer conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.
3. Connect the other end of the cable to the test port and remove the short from the cable.
