U3042AE12 Introduction Introduction This document describes how to use the U3042AE12 Multiport Test Set with the Agilent N5230A/C 4-Port PNA-L Network Analyzer and the N5242A PNA-X for a 16-Port network analyzer solution.
U3042AE12 Description Description The Agilent U3042AE12 Multiport Test Set is a 12-Port solid-state extension test set. When combined with a 4-Port N5230A/C PNA-L or N5242A PNA-X Network Analyzer, the U3042AE12 provides a complete solution for 16-Port full crossbar measurements. The test set is directly controlled by the network analyzer, no external personal computer or software is required.
U3042AE12 Available Options Available Options Test Set Options The U3042AE12 has three available test set options: Refer to “System Block Diagram” beginning on page 85. • Standard - solid state switches for fast switch speed and improved switch life. (No Option 001 or 002 on the serial tag). • Option 001 solid state switches with amplifiers to improve dynamic range. • Option 002 solid state switches with amplifiers and bias-tees for each port.
U3042AE12 Verifying the Shipment Verifying the Shipment Inspect the shipping container. If the container or packing material is damaged, it should be kept until the contents of the shipment have been checked mechanically and electrically. If there is physical damage refer to “Contacting Agilent” on page 94. Keep the damaged shipping materials (if any) for inspection by the carrier and an Agilent Technologies representative. Table 1 contains the accessories shipped with your U3042AE12.
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. 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.
U3042AE12 General Specifications Environmental Requirements The environmental requirements of the PNA are listed in Table 3. Note that these requirements are the same as those of the N5230A/C PNA-L. The N5230A/C PNA-L provides front panel access to the source outputs, receiver inputs and couplers for use with the Multiport test sets. Ventilation Requirements: When installing the instrument in a cabinet, the convection into and out of the instrument must not be restricted.
U3042AE12 General Specifications Dimensions and Space Requirements Standard installation of the U3042AE12 and PNA includes configuration and installation on a customer provided lab bench or table top of adequate size and strength. Table 4 System Dimensions Item Weight Required Bench Top Dimension: Clearance above the bench 43 cm (17 in) Width 127 cm (50 in) Depth 102 cm (40 in) Weight 55 kg (110 lb) Table 5 Instrument Dimensions Model Weight Height Width Depth N5242A 37 kg (82 lb, ±0.

U3042AE12 Theory of Operation Theory of Operation The following is a description of the operation of the U3042AE12. Reference the U3042AE12 block diagrams shown in Figure 67 on page 85. This section assumes the user has a general understanding of couplers, switches, and network analyzers. RF Switch Components There are eight quad switches. The switches select the RF paths from the PNA source and receiver through interconnect cables to test set port paths 5 thru 16.
U3042AE12 Theory of Operation S301 - Receiver to Ports (3, 7, 11 and 15) Switch 301 provides control of the A Receiver path to PNA Port 3 and ports 7, 11 and 15 to the Test Set. In the state shown in the block diagram, switch 301 routes the Coupler Arm from the PNA Port 3 to the A Receiver and all unused Test Set ports (7, 11 and 15) Coupler Arm paths are terminated.
