Preparing the Analyzer for Use

To connect the sections

Do NOT use the IF section’s EXT REF OUT connector or optional OVEN REF OUT connector as an external reference output.

1Attach the IF section to the RF section.

If the hardware is not installed, follow the instructions supplied with the Rear Panel Lock Foot Kit. If the hardware is already installed, slide the IF section on top of the RF section making sure the front lock-links engage the IF section’s frame. Screw the rear lock feet together.

2Connect the RF section’s SERIAL 2 port to the IF section’s SERIAL 2 port using the supplied serial interface interconnect cable. Make sure the end of the cable with the EMI suppressor is conected to the IF section.

3Connect the RF section’s OVEN REF OUT connector to the EXT REF IN connector using the supplied coax BNC-to-coax BNC connector.

If the RF section does not have the OVEN REF OUT connector (option AY4, Delete High Precision Frequency Reference), connect a 1 MHz, 2 MHz, 5 MHz, or 10 MHz sine or square wave, with an amplitude greater than 0 dBm to the RF section’s EXT REF IN connector. For best residual phase-noise, use 10 MHz with an amplitude greater than or equal to 5 dBm. See the Technical Data publication in the beginning of your Installation and Verification Guide for specifications that require the high precision frequency reference.

4Connect the RF section’s 10 MHz REF TO IF SECTION connector to the IF section’s EXT REF IN connector using the supplied 12-inch BNC-to-BNC cable.
