Chapter 1 Getting Started This chapter contains general information on the operating features of the E8402A and E8404A C-Size VXI mainframes. The following table lists the major differences between these two mainframes: Power Supply Enhanced 500 W 1000 W Monitor á...
Page 17: Preparing Your Vxi System For Use
Preparing Your VXI System for Use The Agilent E840xA mainframes are shipped from the factory ready to use. This section describes important mainframe installation procedures. AC Power The Agilent E840xA mainframes can be operated at line voltages of 90 VAC to 264 VAC, and line frequencies of 47 Hz to 66 Hz. The Requirements mainframe can also operate at 360 Hz to 440 Hz with line voltages of 90 VAC to 132 VAC.
Page 18: Connecting The Mainframe To A Permanent Earth Ground
Connecting the The mainframe must be connected to a permanent earth ground for line frequencies greater than 66 Hz. This connection is made on the back of the Mainframe to a mainframe: Permanent Earth 1. Connect a 16 AWG (1.3 mm or larger) wire to the PEM nut shown in Ground Figure 1-1.
Page 19: Installing Vxi Instruments
Installing VXI Instruments The Agilent E840xA mainframes have 13 slots labeled 0 through 12. Any VXI instrument can be installed in any slot; however, slot 0 is reserved for devices capable of providing the system’s slot 0 functionality. This functionality includes: •...

Page 24: Using The Remote Power-On Pins
Using the Remote The remote power-on pins (pins 5 and 18) of the Diagnostic Connector allow you to turn the mainframe on and off without using the front panel On/Stdby Power-On Pins switch. With the On/Stdby switch in the Stdby (off) position, connecting pin 5 to pin 18 on the diagnostic connector turns the mainframe on.

Page 30: Using The Enhanced Monitor
Using the Enhanced Monitor The Enhanced Monitor is a separate PC board that plugs into the VXI backplane from the rear of the mainframe. In this way it does not occupy a user slot on the front of the mainframe. The Enhanced Monitor uses a standard-defined P1 Connector but a uniquely-defined P2 Connector.
Page 31 • Voltage Monitor measures all seven power supply voltages (+5, ±12, ±24, -5.2V, and -2V). -- Voltages outside of fixed limits (based on VXI specifications) causes the monitor to generate a warning on the display, set a status bit, the Power Supply LED flashes, and the beeper sounds (if enabled).

Page 35: Enhanced Monitor Fan Control
Enhanced Monitor Fan Control With the front panel fan switch in the VAR position, the Enhanced monitor controls the fan speed based on slot temperature limits you specify. With the fan switch in the FULL position, the fan operates at full speed. Essentially, the Enhanced Monitor’s fan control has two contrasting functions: 1) keep the VXI modules installed in the cardcage cool and 2) operate as quietly as possible.
Page 36: Setting Enhanced Monitor Limits
Setting Enhanced Monitor Limits The Agilent E840x Enhanced Monitor has several limits that affect when it will issue warnings. Each limit should be selected based on the VXI modules installed in the mainframe. Temperature Limits The Enhanced Monitor monitors two types of temperature limits. First are the "Delta slot temperature limits"...
Page 37: Handling Warnings
Handling Warnings With the limits set, the mainframe will beep if a limit is exceeded. However, you need to include exception procedures in your computer program so that the program can handle the warnings. To do this, you need to enable the Enhanced Monitor’s Status Subsystem to interrupt the computer when a warning occurs.
Page 38: Using The History Queue
Using the History Queue The Agilent E840x Enhanced Monitor provides many history feature records such as: minimum and maximum values, histograms, operating times, and event logs. As you begin to use the mainframe, the history features won’t be of much use -- very little has happened, there is no history to record.
Page 39: Rs-232 Programming
RS-232 Programming The RS-232 port on the Enhanced Monitor is primarily a debug port, designed for use with a dumb terminal or terminal emulator program on a PC. This allows you to execute SCPI commands directly without an application program and to monitor any errors in the error queue (including those generated through the VXI interface programming).
Page 40 The Enhanced Monitor also provides several short cuts, primarily for terminal use: Backspace In TERMinal mode, a backspace means "back-up." It becomes a space in RAW mode. Ctrl-R In TERMinal mode, this provides a "recall last command string" feature. It is ignored in RAW mode Ctrl-T In either TERMinal or RAW mode, Ctrl-T performs a SYSTem:COMMunication:PRESet:TERMinal...

For Commands shorter program lines, send the abbreviated form. For better program readability, you may send the entire command. The instrument will accept either the abbreviated form or the entire command.
Page 46 Agilent VISA library, an Agilent-IB interface module installed in an external PC, an Agilent E1406 Command Module, and the enhanced monitor in either the Agilent E8402A or E8404A VXI mainframe. The following program examples are developed with the ANSI C language using the Agilent VISA extensions.

Page 87: Status Subsystem
STATus Subsystem SCPI uses four status groups - the Status Byte, the Standard Event status group, the Operation status group, and the Questionable Data status group. The STATus subsystem controls those command (and queries) that affect the OPERation status group and the QUEStionable status group. The OPERation status group provides information about the state of the monitoring systems in an instrument.

This includes the Standard Event Status register, the OPERation event status register, and the QUEStionable data status register. • *CLS does not affect the enable bits in any of the status register groups.

If any other value is returned, a defective temperature sensor exists. execute the command TEST:RES:VERB? to get a detailed string description of the problem 7.

For Calibration, start by storing the reference voltage by sending the <supply>,<value> command.

Old values will be used otherwise. If you want the calibration routine to calculate a temperature calibration value you MUST send a CAL:VAL:TEMP -1 before every calibration command.

                                        CALibration:TEMPerature? performs the temperature-related calibration CALibration:TEMPerature? procedures. Calibration is performed assuming the mainframe is in these conditions: no modules loaded, mainframe at a steady state temperature in a constant temperature environment (fan switch set to FULL for at least ten minutes). This means that this command should always be issued through the RS-232 interface.

CALibration:VALue:TEMPerature <value> provides the enhanced monitor with an externally measured temperature measured at a sensor inside the mainframe in a constant temperature environment with no modules installed in the mainframe. The value will be used to calibrate each temperature sensor of the enhanced monitor.
