Installation at a Glance

The installation procedure is composed of the following basic steps:
1. If you just purchased an antenna measurement system, install all
components as described in the documentation that came with that
system. Do not connect the Agilent 85330A yet.
2. Turn on the system and perform a functional check.
3. If desired, verify the performance of the system components by referring
to the Performance Verification chapter of the system manual.
4. Install and verify the 85330A system as explained in this manual.
Installation

Preparing the Main Antenna Measurement System

Preparing the Main Antenna Measurement
System
CAUTION As an antistatic precaution, do not touch exposed connector contacts!
Information about installing, performing an operational check, and verifying the main antenna measurement system is explained in the appropriate documentation listed below:
• Agilent 85301B Antenna Measurement System Manual
• Agilent 85301C Antenna Measurement System Manual
• Agilent 85310A Distributed Frequency Converter Manual
If you purchased an Agilent 8511 as a stand-alone unit, refer to the Agilent 8530A On-Site Service Manual for installation instructions. Verify the 8511
as explained in its operating and service manual.
Choosing the Proper Configuration
Installing the Agilent 85330A Multiple Channel
Controller
There are two ways to install the Agilent 85330A system. Figure 1-1 on
page 1-3 is a flow chart that shows a installation configuration that is
appropriate for you to use.
How to use the figure
Follow the flow chart from the top. Determine if your measurements are made with a single frequency (CW), or multiple frequencies. Proceed down the appropriate flow chart path. Proceed in this way until you get to a box that recommends either Figure 1-2 on page 1-4, or Figure 1-3 on page 1-5.
Fast Source Control
Fast source control speeds up frequency switching speed in multiple-frequency measurements. It is only available in systems that use two Agilent 836xx series synthesized sources. This mode uses TTL signals to increment RF and LO source frequency, providing faster frequency switching speeds than are possible under 8530A control. In the fast source control configuration, the system’s computer must set up the sources with appropriate frequency settings, triggering mode, and so on. When automatic Run Time measurement mode is engaged, the 85330A automatically increments the RF and LO source frequencies using TTL lines. More information is provided in Chapter 6, “Programming.” When the sources are controlled by a computer, the SCPI language mode must be selected. This is shown in Figure 1-3 on page 1-5.

Checking Operation of the Multiple Channel Controller

Checking Operation of the Multiple Channel
Controller
Turn the multiple channel controller ON; the following screen should appear:
Select an instrument._ SYSTEM 85330A IBASIC
NOTE IBASIC is only present if the IBASIC option is installed.
If the display shows loaded.
If you do not see this display, load the VXI mainframe downloadable driver files as explained in “Loading the Driver from a Personal Computer,” next.
The 85330A contains 85330A driver files from the disk labeled 85330A Downloadable Driver Disk. When your system was shipped, the driver files were already loaded into the non-volatile memory of the 85330A mainframe. Once loaded, it will remain when the mainframe is powered down or when the power is interrupted to the mainframe.
If you must reload the drivers, a complete set of instructions are included in the
INSTALL.TXT file on the supplied driver disk, or perform the following
instructions:
NOTE This method uses a personal computer (PC) to download the drivers over a
serial cable (supplied).
(see note below)
“DIG I/O” instead of “85330A”, then the drivers are no longer
NOTE The downloadable driver disk should not be set to the write-protected
position or the driver files will not load properly.

Loading the Driver from a Personal Computer

Equipment Needed
The following equipment was supplied with your system:
• Serial Cable: 24542U part number 24540-80014, 9-pin to 9-pin
• Adapter: 1252-7577, 9-pin to 25-pin (only needed if your computer has
a 25-pin serial connector)
• Downloadable Driver Disk: p/n 85330-10016 (rev A.02.31 or higher)
Installation
Checking Operation of the Multiple Channel Controller
NOTE You can use other com ports, such as com2. However, you have to edit a file
called
“VXIDLD.CFG” so the software knows you are using a different port.
This configuration file can be edited with any ASCII text editor, such as notepad. Save the changed file back to the supplied disk.
NOTE Agilent recommends that you make two backups of the driver disk. Make
one copy to a floppy disk, and one copy to the personal computer used with the system.
Procedure
NOTE This procedure may not work on later versions of Microsoft®1 Windows®
such as Windows NT® and Windows 2000®.
1. Disconnect any GPIB cables from the mainframe. If it is easier, you can
disconnect the GPIB from the back of the system controller computer.
2. Turn the VXI mainframe ON.
3. On your PC, open a DOS command prompt window.
4. Insert the supplied driver disk into drive A. (Do not write-protect the
downloadable driver disk. The driver will not load if the write-protect
window is open. Make sure the tab is snapped fully into the closed
portion.)
5. In the DOS command prompt window, change to drive A.
6. In the DOS command prompt window, type
VXIDLD and press [Enter].
7. The mainframe download procedure takes approximately six or seven
minutes, and the mainframe will reboot.
NOTE There are several error messages that can be ignored. These are described in
the README.TXT file on the driver disk. Specifically, refer to the description of the VXIDLD.CFG file.
8. Reconnect all the GPIB cables.
9. When finished, the following should be displayed:
Select an instrument._

Selecting Positive or Negative-Edge Event
Triggers
By default, the positive-edge of the EVENT TRIG line starts the measurement. To change this so a negative-edge starts the measurement, perform the following procedure.
CAUTION This device contains devices that are sensitive to static discharge. When you
remove the cover of this device, observe static safety precautions:
1. Place the unit on a grounded anti-static mat.
2. Wear a grounded wrist strap. Foot straps are only acceptable if you wear one on each foot, and if you are standing on a grounded floor mat.
Refer to Figure 1-4 on page 1-9.
Installation
Selecting Positive or Negative-Edge Event Triggers
Figure 1-4 Positive/Negative-Edge EVENT TRIG jumpers
1. Remove the two screws that hold the E1330B board in place.
2. Remove the four screws that hold the 85330-60002 board in place.
3. Pull out the two boards at the same time. You can do this by pulling each one out a little at a time, until they are both removed. Place the boards
on an anti-static surface.
Standard positive-edge operation is set at the factory by jumpering E9 and E10 together.
4. To select negative-edge operation, move the jumper across E9 and E8.
5. Reinstall the boards and screws.

MountingtheSCU and RF Switch

NOTE Make sure the 85383A local control cable can reach from the multiple
Switch Control Unit Configuration Switches
If desired, you can mount the SCU using the supplied mounting screws. You must provide a mounting plate or drill holes in an existing structure before mounting an SCU or a switch. Refer to the mounting diagram in Figure 1-5
on page 1-11.
channel controller to the SCU. Make sure the 85384A switch drive cable is long enough to reach from the SCU to the switch.
Changing any of the DIP switches inside the SCU is not recommended. All switch settings are made at the factory.
In a standard system (defined below), the following settings are used:
• SCU address is set to 0.
• Channel numbers 1 through 4 are used to select switch positions.
A “standard system” uses one 85330A with one or two switch control units, each with a two-throw or four-throw switch module. Remember that 85330A PORT 1 and PORT 2 are addressed independently. So:
• If you have two SCUs, both can use the default SCU address (0).
• You can use the default channel number assignments (1 through 4) for
both switch modules. Since each SCU is on a different port, and each port is addressed independently, there is not a channel number conflict.
