When the channel dis- play is on, a waveform is displayed for that channel, unless the offset is adjusted so the waveform is clipped off the display. The channel number, vertical scaling, and offset are displayed at the bottom left of the waveform area.
  • Page 29 The fine mode also works with offset. When an HP 54700-series active probe is connected to the probe power con- nector, the offset control adjusts the external scale factor and offset of the hybrid inside the active probe.

  • Page 31 Channel Setup Menu Channel autoscale Channel autoscale The Channel autoscale softkey provides a convenient and fast method for deter- mining the standard vertical scale setting with the highest resolution that will not clip the waveform. Timebase and trigger settings are not affected. This function is useful in manufacturing environments where the timebase and trigger settings remain constant and only the vertical scale needs to be adjusted for signal level variations in multiple devices under test.

  • Page 38 Proper calibration is critical to measurement accuracy and repeatability. The HP 54750A/83480A and their associated modules and accessories require that both factory and user calibrations be implemented at the recommended inter- vals in order to perform measurements at their published specifications.
  • Page 39 To maintain specifications, periodic recalibrations are necessary. We recommend that the plug-in module be calibrated at an HP ser- vice facility every 12 months. Users are encouraged to adjust the calibration cycle based on their particular operating environment or measurement accu- racy needs.

  • Page 42 The accuracy of all optical channel measurements is dependent on proper O/E calibration. O/E calibrations should be performed annually. Most customers return their optical plug-ins to an authorized HP ser- vice center for this calibration at the same time they are having their main- frames re-calibrated.

  • Page 46 For best results, measure the optical source power with an optical power meter such as the HP 8153A and use precision optical connectors. In addition, proper connector cleaning procedures are essential to obtaining an accurate calibration.
  • Page 47 Calibration Overview User Calibrations—Optical and Electrical Plug-in Module Vertical Calibration The plug-in module vertical calibration is for both optical and electrical mea- surements. It allows the instrument to establish the calibration factors for a specific plug-in when the plug-in is installed in the mainframe. The plug-in cal- ibration factors are valid only for the specific mainframe slot in which it was calibrated.
  • Page 48 If you are prompted to connect the calibrator output to the electrical channel during an optical vertical calibration, then the factory O/E calibration has been lost. The module must then be returned to HP for calibration. Offset Zero Calibration The offset zero calibration performs a quick offset calibration on the optical channel for optical measurements.
  • Page 49 Calibration Overview User Calibrations—Optical and Electrical Figure 3-3. Offset Zero Calibration Dark Calibration The dark calibration is for optical measurements, or electrical measurements if an external O/E is being used. This calibration measures the optical channel offset signal when there isn’t any light present and then uses this information in performing extinction ratio measurements.
  • Page 50 Calibration Overview User Calibrations—Optical and Electrical To initiate a dark calibration 1 Press the Display key. Press the Color grade softkey, and set its setting to on. Color grade must be enabled to perform an extinction ratio measurement and a dark calibration. In addition, the dark level (amplitude when there is no signal present) must be on the screen to perform a dark calibration.
  • Page 51 Probe Calibration Probe calibration applies to electrical measurements only. For active probes such as the HP 54701A, which the instrument can identify through the probe power connector, the instrument automatically adjusts the channel vertical scale factors to the probe’s nominal attenuation, even if a probe calibration is not performed.
  • Page 52 You can use the probe calibration to calibrate any network, including probes or cable assemblies. The instrument calibrates the voltage at the tip of the probe or the cable input. To calibrate an HP identifiable probe 1 Press the plug-in module’s front-panel-channel SETUP key. 2 Press Calibrate and then Calibrate Probe.
  • Page 53 Calibration Overview User Calibrations—Optical and Electrical Figure 3-5. Electrical Channel Calibrate Menu To calibrate other devices The information in this section applies to both optical and electrical measure- ments. Since the mainframe’s CAL signal is a voltage source, it cannot be used to calibrate to the probe tip when the units are set to Ampere, Watt, or Unknown.
  • Page 54 Calibration Overview User Calibrations—Optical and Electrical External Scale Both optical and electrical channels have an External scale setting which allows the user to enter in an offset value to compensate for gains or losses not associated with the device under test. This feature is useful for adjusting out the effects of devices such as test fixtures and attenuators so that the reading on the display gives the measurement value associated with only the actual device under test.

  • Page 82: Cleaning Connections For Accurate Measurements

    Reference Cleaning Connections for Accurate Measurements Cleaning Connections for Accurate Measurements Today, advances in measurement capabilities make connectors and connec- tion techniques more important than ever. Damage to the connectors on cali- bration and verification devices, test ports, cables, and other devices can degrade measurement accuracy and damage instruments.
  • Page 83 HP instruments typically use a connector such as the Diamond HMS-10, which has concentric tolerances within a few tenths of a micron. HP then uses a spe- cial universal adapter, which allows other cable types to mate with this preci- sion connector.

  • Page 85 Reference Cleaning Connections for Accurate Measurements The soft core, while allowing precise centering, is also the chief liability of the connector. The soft material is easily damaged. Care must be taken to mini- mize excessive scratching and wear. While minor wear is not a problem if the glass face is not affected, scratches or grit can cause the glass fiber to move out of alignment.
