Attaching the Power Module and Power Cords

1. Attach the power cord module (found in the accessories carton) to
the rear-upper cart support. Use the metal posts located on the far
right-hand side of the cart when viewed from the rear of the cart.
The power cord module is grooved to slip over the metal posts.
2. Plug the power cord into the power module for the two ampli er
power supplies (located on the bottom of the tiltable shelf).
3. Plug in the EMC analyzer using one of the 30-inch power cords.
4. Attach the 8-foot long power cord supplied with the system to the
power cord module.
Notice that the input end of this cable is speci c to the country
receiving the system. Before connecting the system to a power
source, make sure that the EMC analyzer line module is con gured for
the proper voltage requirements. Refer to Chapter 1 of the HP 8590
EM Series EMC Analyzer User's Guide for complete instructions.

Installing the Accessories and Test Set in the System

1. Open the drawer of the cart and remove all of the contents except
the foam ller. Position the foam ller at the back of the drawer.
2. Remove the shipping foam with the accessories from the accessory
carton and place it in the front of the drawer. This is a convenient
place to store the system hardware.
3. Remove the test set with its attached three-meter RF cable
assembly from the smallest carton and place it on top of the EMC
analyzer. Position the analyzer handle so that it rests against the
back of the analyzer.
4. The test-set carton also contains the HP 84125A/B RAM card for
the EMC analyzer. Install the RAM card into the memory card slot
located underneath the analyzer display. To install the RAM card:
a. Position the card with the label facing upwards.
b. Press the card into the slot. When correctly inserted, about
19mm (0.75 in) of the card is exposed from the slot.

Performing an EMC Analyzer Calibration

Data from the self-calibration routine is necessary for proper
operation of the EMC analyzer. Executing the self-calibration routine
ensures that the EMC analyzer is using current calibration data that
improves the EMC analyzer frequency and amplitude accuracy. The
EMC analyzer should be turned on and allowed to warm up for at
least 30 minutes before performing the self-calibration routine or
attempting to make any measurements. The addition of the correction
factors is required to meet frequency and amplitude speci cations.
This is a convenient point in the system installation to perform an
EMC analyzer calibration, since the RF cable assembly is not yet
connected to the INPUT 50 of the analyzer.
Refer to \Calibrating the HP 8593EM EMC Analyzer" in Chapter 6 to
perform a frequency and amplitude calibration.
