The purpose of the plug-in module The purpose of the plug-in module is to provide measurement channels, including sampling, for the mainframe.
The Instrument at a Glance The Electrical Plug-In Modules Figure 1-1. Front panel of the plug-in module. Getting the best performance To ensure you obtain the specied accuracy, you must perform a plug-in module vertical calibration. The calibration must also be performed when you move a plug-in module from one slot to another, or when you move a plug-in module from one mainframe to another.
The Instrument at a Glance Installing the plug-in module You do not need to turn o the mainframe to install or remove the plug-in modules. The plug-in module can be installed in slots 1 and 2 or 3 and 4 on the Agilent 83480A, 54750A mainframe.

Channel Setup Menu Displaying the Channel Setup menu To display the Channel Setup menu, press the key. Channel Display aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa The Display softkey turns the channel display o and on. When the channel display is on, a waveform is displayed for that channel, unless the oset is adjusted so the waveform is clipped o of the display.
Channel Setup Menu Scale aaaaaaaaaaaaaaaaaaaaaaaaaa The Scale softkey controls the vertical scaling of the waveform. If the ne mode is o, then the knob and arrow keys change the vertical scaling in a 1-2-5 sequence. When ne mode is on, the knob and arrow keys change the vertical scaling in 1 mV increments.
Channel Setup Menu Bandwidth. . . aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa Agilent 83483A, 54751A only You can use the Bandwidth function to select either the 12.4 GHz or the 20 GHz bandwidth.

Channel Setup Menu NNNNNNNNNNNNNNNNN The Units function lets you select the unit of measure appended to the Units channel scale, oset, trigger level, and vertical measurement values. For the plug-in module, the units are Volts, Amperes, Watts, or unknown. Use Volt for voltage probes, Ampere for current probes, Watt for optical-to-electrical (O/E) converters, and unknown when there is no unit of measure or when the unit of measure is not one of the available choices.
Channel Setup Menu Calibrate aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa The calibrate menu allows you to null out any skew between probes or cables and check the present calibration status of the instrument.

Guide Agilent or the electrical module calibration using the optional 83483A/4A/4B, 54751A/2A/2B Service Guide The second part of the chapter addresses calibrations that are routinely performed by the end user. Subsections in each of the two main sections discuss the individual calibrations. In addition, there will be summary tables at the end of each of these sections summarizing the main areas addressed.
Page 39
To maintain specications, periodic recalibrations are necessary. We recommend that the plug-in module be calibrated at an Agilent Technologies service facility every 12 months. Users are encouraged to adjust the calibration cycle based on their particular operating environment or measurement accuracy needs.
Factory Mainframe Calibrations Mainframe calibration (performed at the factory) improves timebase accuracy. All timebase measurements such as rise time, fall time, eye width, jitter, and so forth are aected by the timebase accuracy. The calibration factors are stored in the nonvolatile RAM of the instrument. There is a switch on the back panel of the instrument that allows the mainframe calibration to be protected or unprotected.
Calibration Overview Factory Mainframe Calibrations The temperature change is displayed at the top of the display as shown in the following gure. Figure 3-1. Current Frame 1Temp condition If the listing is greater than C, then the Current Frame 1Temp mainframe should either be calibrated at the current operating temperature or be placed in an ambient air temperature that is within 5 C of the temperature...
User Calibrations The following calibrations can be performed by the user: Plug-in Module Vertical Calibration Dark Calibration Probe Calibration Channel Skew External Scale Electrical channels have calibration procedures for: adjusting timebase skew, for matching propagation delay between channels, probes, cables, and so forth using external probes The input circuits can be damaged by electrostatic discharge (ESD).

Calibration Overview User Calibrations To obtain the best measurement results, it is recommended that a user vertical calibration be performed after every 10 hours of continuous use or if the temperature has changed by greater than 2 C from the previous vertical calibration.
Calibration Overview User Calibrations If extinction ratio measurements are being made after the vertical scale or the oset has changed. If the line power has been cycled, the dark calibration invokes either the oset zero calibration or plug-in vertical calibration as needed. This increases the time required for the dark calibration to complete.
Calibration Overview User Calibrations Channel Skew Calibration The skew calibration changes the horizontal position of a waveform on the display. The skew calibration has a range of approximately 100 s. You can use skew to compensate for the dierences in cable or probe lengths. It also allows you to place the trigger edge at the center of the display when you are using a power splitter connected between the channel and trigger inputs.
Calibration Overview User Calibrations The analyzer calibrates to the tip of the probe by setting the probe attenuation to the actual attenuation ratio of the probe. The CAL signal is internally routed to the probe tip for Agilent active probes. The mainframe's CAL signal is a voltage source, therefore you can let the instrument compensate for the actual characteristics of your probe by letting the instrument calibrate to the tip of the probe.
Calibration Overview User Calibrations Figure 3-3. Electrical Channel Calibrate Menu To calibrate other Since the mainframe's CAL signal is a voltage source, it cannot be used devices to calibrate to the probe tip when the units are set to Ampere, Watt, or Unknown.
Page 49
Calibration Overview User Calibrations External Scale There is an External scale setting which allows the user to enter in an oset value to compensate for gains or losses not associated with the device under test. This feature is useful for adjusting out the eects of devices such as test xtures and attenuators so that the reading on the display gives the measurement value associated with only the actual device under test.
