Safety Summary When you notice any of the unusual conditions listed below, immediately terminate operation and disconnect the power cable. Contact your local Agilent Technologies sales representative or authorized service company for repair of the instrument. If you continue to operate without repairing the instrument, there is a potential fire or shock hazard for the operator. n Instrument operates abnormally. n Instrument emits abnormal noise, smell, smoke or a spark-like light during the operation.
Caution Do not exceed the operating input power, voltage, and current level and signal type appropriate for the instrument being used, refer to your instrument's Function Reference. Electrostatic discharge(ESD) can damage the highly sensitive microcircuits in your instrument. ESD damage is most likely to occur as the test fixtures or cables are being connected or disconnected. Protect them from ESD damage by wearing a grounding strap that provides a high resistance path to ground.

Unpacking and Checking the Contents of the Shipment 1 This chapter describes how to check the shipping container of your 43521A ( Downconverter Unit), the appearance of the product, and the contents of the shipment. Incoming Inspection When you receive the product, inspect the shipping container for damage.
2 Connecting 43521A The 43521A (Downconverter Unit) is used as part of the 4352S (VCO/PLL Signal Test System). Using the 43521A expands the maximum frequency of the 4352S to 12.6 GHz. This chapter describes how to make connection for the 4352S when associated with the 43521A. How to use the entire 4352S including the 43521A is described in Chapter 5 of the 4352B Function Reference, while a quick guide to diagnosis is provided in Appendix F of that document.
Conditions Rear 180 mm Side 60 mm Instruction for Cleaning To prevent electrical shock, disconnect the 43521A's power cable from the power outlet before cleaning. To clean the exterior of the 43521A, wipe the surfaces with a dry cloth or a soft cloth that is soaked with water and wrung tightly, without undue pressure. Do not attempt to clean the 43521A internally.
Connections on the Front Panel Make connections as shown in Figure 2-1. For how to connect a DUT (Device Under Test), refer to Chapter 5 of the 4352B Function Reference. Figure 2-1. Connections on the Front Panel No. Name 1 N-N cable (18 cm x 2) 2 N-N cable Table 2-1.
Connections on the Rear Panel Make connections as shown in Figure 2-2. Figure 2-2. Connections on the Rear Panel No. Name Table 2-2.
Power Requirements Ratings of the Power Source The 43521A requires the following power source: Voltage : 90 to 132 Vac or 198 to 264 Vac Frequency : 47 to 63 Hz Power : 100 VA maximum Power Cable In accordance with international safety standards, this instrument is equipped with a three-wire power cable. When connected to an appropriate ac power outlet, this cable grounds the instrument frame. The type of power cable shipped with each instrument depends on the country of destination.

1. RF Input Connector Receives the RF output signal from the device under test (signal to be measured). INSTALLATOIN CATEGORY I 2. RF Output Connector The RF signal (signal to be measured) inputted to the RF input connector is outputted from this connector, and sent to the RF input connector of the 4352B (VCO/PLL Signal Analyzer) through the N-N cable.
Rear Panel Figure 3-2 shows the con guration of the rear panel. Figure 3-2. rear panel 1. 40 MHz Input Terminal To improve the frequency accuracy of the 600-MHz signal inside the 43521A, the 40-MHz signal from the rear panel of the 4352B (VCO/PLL Signal Analyzer) is inputted to this connector to provide phase locking for synchronizing the 600-MHz signal to the 40-MHz signal. 2. I/O Port Receives the digital signal from the I/O port connector on the rear panel of the 4352B.
Replacing the Fuse Select a proper fuse according to the Table 3-1. Table 3-1. Rating of Fuse Rating Part Number 3A 250Vac UL/CSA type Time delay 2110-0381 For ordering the fuse, contact your nearest Agilent Technologies Sales and Service O ce.
