    Instrument Markings Contacting Keysight Returning the Instrument for Service The Keysight Technologies N109X-series DCA-M sampling oscilloscopes combine the high-performance elements of both the DCA-X oscilloscope mainframe acquisition system and the hardware of a receiver plug-in module. The N1010A FlexDCA application provides both the Graphical User Interface (GUI) as well as programming interface either on a PC or on a DCA-X (N1000A or 86100D).
  • Page 6 1 Introduction Figure 1. USB Connections to PC or N1000A (or 86100D) With a DCA-M, you can perform eye-mask tests, measure eye diagram parameters including extinction ratio, and basic oscilloscope mode measurements of pulses (single-valued waveforms rather than eye diagrams). This is limited to patterns less than 2 ns in duration.

  • Page 46: Static-Safe Workstation

    2 Installation and Care Static-Safe Workstation Electrostatic discharge (ESD) can damage or destroy electronic components. All work on instruments and electronic components should be performed at a static-safe workstation as shown in Figure 18. The static-safe workstation uses two types of ESD protection: Conductive table-mat and wrist-strap combination.
  • Page 47 2 Installation and Care Only the table-mat and wrist-strap combination provides adequate ESD protection when used alone. To ensure your safety, the static-safe accessories must provide at least 1 MΩ of isolation from ground. Purchase acceptable ESD accessories from your local supplier. Electrical channel input circuits and the trigger input circuit can be damaged by electrostatic discharge (ESD).
  • Page 48 2 Installation and Care 6. Visually check that all ESD sensitive parts, assemblies, or products are com- pletely inside closed conductive containers. 7. Make sure that all shielding containers have an approved static attention label on the outside. 8. Make sure that all cleaners, solvents, coatings, and sprays used at your workstation are types approved by your ESD Coordinator.

Many products are available and are easily located via an internet search on "fiber optic cleaning products". You can purchase tools designed specifically for the type of fiber-optic connector that you are using.
  • Page 50 Cleaning Optical Connections Keysight instrument fiber-optic input and output connectors often employ either lever adapters (for example on an N1090-series DCA-M) or screw-on universal adapters (for example on an 86105C). These adapters, when removed, have no fiber-optic parts and can be cleaned using the procedure in this topic.

    3 Using To Setup the Oscilloscope This example shows an N1092D-series sampling oscilloscope. You can substitute any N109X-series oscilloscope. The input Clock In signal must be a synchronous clock or sub-rate clock. The N109X-series oscilloscope will trigger with any clock signal between 100 MHz and 32 GHz. In this procedure, the following assumptions are made for simplicity.

  • Page 59: Reference Clock

    3 Using Reference Clock Like a DCA-X, for proper display of the input signal the input Clock In signal must be a synchronous clock or sub-rate clock. The N109X-series oscilloscope will trigger with any clock signal between 100 MHz and 32 GHz. The clock input range for the N1090A is 455 MHz to 12 GHz, and the N1092 is 500 MHz to 28.5 GHz.

These reference filters allow for optical transmitter compliance testing at the listed filter rates.

  • Page 63: Aligning Waveforms

    3 Using Aligning Waveforms Because a DCA-M’s acquisition system is independent of the DCA-X, if you are using multiple DCA-Ms or a DCA-M with DCA-X receiver modules, the input waveforms may not align after an Auto Scale. The waveforms will align If option 500, Productivity Package Software, is installed on the DCA-X or DCA-M and Rapid Eye is turned on.

    3 Using Cleaning the Fiber-Optic Connectors Keep all fiber-optic connectors clean using professional fiber-optic cleaning products. Many products are available and are easily located via an internet search on "fiber optic cleaning products". You can purchase tools designed specifically for the type of fiber-optic connector that you are using. Replacing a damaged fiber-optic connectors can cost thousands of dollars, not to mention lost time! This expense can be avoided by observing the important precautions described in this topic.

    4 Programming Aligning Waveforms Because the acquisition system on N109X-Series DCA-M Oscilloscopes is independent of a DCA-X, if your are using multiple DCA-Ms or a DCA-M with 86100D receiver modules, the input waveforms may not align after an Auto Scale ( .

  • Page 72: Precision Time Base

    4 Programming Precision Time Base Because a DCA-M has different hardware than the DCA-X, N109X-series DCA- M oscilloscopes do not work with a Precision Time Base (PTB). However, an N109X-series DCA-M oscilloscope with option LOJ (Low Jitter Timebase) does provide PTB performance without the need for special commands. Therefore, the following FlexDCA commands do not work with DCA-M oscilloscopes: :CALibrate:FRAMe:PTIMebase:STARt :CALibrate:FRAMe:PTIMebase:STATus?

  • Page 73: Recommended Best Practices

    4 Programming Recommended Best Practices The following techniques explicitly set values for selecting an optical channel’s wavelength or filter rate. These methods are recommended for both DCA-M and DCA-X oscilloscopes. Optical wavelength selection commands :CHANnel:WAVelength To specify an input channel’s wavelength, it is recommended that you do not use the command.
  • Page 74 4 Programming This is because the definition of the filter argument can differ between modules and module options. For example, the argument can specify a different FILTer2 filter based on DCA-M oscilloscope or standard module and with different reference filter rate options. For example, it might be 8.5 Gb/s in one case and 9.953280 Gb/s in another.

    4 Programming Finding the VISA Address for HiSLIP The VISA Address for the HiSLIP interface is easy to locate and is used to identify the LAN address between your program and FlexDCA. 1. On FlexDCA, click the menu commands Tools > SCPI Programming Tools. The SCPI Server Setup dialog box opens as shown below.

    Python scripts in this book are relatively simple, so you should be able to convert them to 2.x is you prefer to work in Python 2.x. 1. Install Keysight IO Libraries Suite. Download the suite from http://www.key- sight.com/find/iosuite. 2. Go to https://www.anaconda.com/distribution/ and download and install the current Python 3 Anaconda distribution.

General Information on the Scripts print() statements The Python 3.x statement is used to provide messages on the script’s print() progress to the user.

Identify all connected DCA-Ms and modules The following Python script discovers all DCA-M oscilloscopes, standard modules, and simulated modules and prints their model numbers to the console. The script uses the query to return the model :SYST:MODel? SLOT number of a standard or DCA-M module.

The script in DCA_M_reorder.py on page 95 first disconnects any existing DCA-Ms and deletes any simulated modules. The script then connects up three DCA-Ms (dictionary values) in the desired slots (dictionary keys).

Perform eye measurement with N109X & N1076/7A This Python example uses an N1076/7A clock recovery in slot 5 to provide a clock for an N109X-series DCA-M oscilloscope in slot 6. A bit-rate eye measurement is performed on channel 6A. The program performs the following tasks: Places FlexDCA to its default settings.
