EC Declaration of Conformity – EMC

Meets intent of Directive 89/336/EEC for Electromagnetic Compatibility when configured with sampling head modules designed for use with this instrument as identified in this manual. Compliance was demonstrated to the following specifications as listed in the Official Journal of the European Union:

EN 61326 EMC Requirements for Electrical Equipment for Measurement,

Control and Laboratory use.

Class A Radiated and Conducted Emissions IEC 1000-4-2 Performance Criterion B IEC 1000-4-3 Performance Criterion A IEC 1000-4-4 Performance Criterion B IEC 1000-4-5 Performance Criterion B IEC 1000-4-6 Performance Criterion A IEC 1000-4-11 Performance Criterion B

Performance Criteria C for USB keyboard and mouse. Note that operation of the

1,2 1 1 1 1 1

USB keyboard and mouse can be restored by unplugging and then reconnecting the USB connector at the rear panel of the main instrument.

Horizontal timing susceptibility of the optical sampling modules and their internal clock recovery trigger signals usually increase the horizontal timing jitter when external electromagnetic fields are applied. For fields up to 3 V/m, the increase in the horizontal high-frequency RMS jitter is typically less than 3 ps RMS of jitter, added using the square-root-of-the-sum-of-the-squares method. An example follows:

If an 80C01-CR operating in clock-recovery trigger mode exhibits 3.5 ps RMS of edge jitter, with no EMC field applied and for an ideal jitterless input, then for applied fields up to 3 V/m the edge jitter, degradation would typically result in a total RMS jitter of:

Installation

NOTE. The information found in this section is a subset of the Installation section found in the CSA8000 & TDS8000 User manual.

This section covers installation of the instrument, addressing the following topics:

H Check the Environment Requirements on page 2–1 H Install the Sampling Modules on page 2–2 H Connect the Peripherals on page 2–4 H Power On the Instrument on page 2–5 H Powering Off the Instrument on page 2–7

The basic operating software is already installed on the hard disk. If reinstallation of software becomes needed, see the following topic:

H Software Installation on page 2–7

Check the Environmental Requirements

Read this section before attempting any installation procedures. This section describes site considerations, power requirements, and ground connections for your instrument.

Site Considerations

The instrument is designed to operate on a bench or on a cart in the normal position (on the bottom feet). For proper cooling, at least two inches (5.1 cm) of clearance is recommended on the rear and sides of the instrument.

You can also operate the instrument while it rests stood up on its rear feet. If you operate the instrument while it is resting on the rear feet, make sure that you properly route any cables coming out of the rear of the instrument to avoid damaging them.

CAUTION. Keep the bottom of the instrument clear of obstructions to ensure proper cooling.

Operating Requirements

Rackmount Requirements

Specifications in chapter 1 list the operating requirements for the instrument. Power source and temperature, humidity, and altitude are listed.

If this instrument is rackmounted, see the TDS8000 & CSA8000 Rackmount Instructions for additional site considerations or operating requirements. This document ships with the Option 1 R (rackmount kit).

Install the Sampling Modules

CAUTION. Do not install or remove any sampling modules while the instrument is powered on.

Always power the instrument down before attempting to remove or insert any sampling module.

WARNING. Sampling modules are inherently vulnerable to static damage. Always observe static-safe procedures and cautions as outlined in your sampling module user manual.

Check Your Sampling

Module Manual(s)

The sampling modules that you order with your instrument ship with the appropriate sampling-module user manuals. Read these manuals for instructions on how to install your sampling modules, and then install them as outlined. (Sampling modules do not ship preinstalled.)

NOTE. To find sampling module user manuals, check in the appendices of the

CSA8000 & TDS8000 User Manual if user documentation is available. Users are instructed to insert their sampling-module user manuals there.

NOTE. After first installing a sampling module(s) or after moving a sampling module from one compartment to another, you should run compensation from the Utilities menu to ensure the instrument meets its accuracy specifications. You must run a compensation (accessed from the Utilities menu) whenever the extender configuration is changed from that present at the last compensation. In short, if you install or remove an 80E00 extender, run a compensation. If you exchange a extender for one of a different length, run a compensation. For instructions on running a compensation, see Perform the Compensation on page 4–5.

Powering Off the Instrument

The instrument has a built-in soft power-down function that safely powers down the instrument when you push the On/Standby button. You do not need to close the UI application or Windows 98 before using the On/Standby button.

To completely remove power to the instrument, first soft power-down the instrument using the On/Standby button, and then set the power switch on the rear panel to off.

You can restore the UI application to the screen by clicking its button in the Windows Task bar.

Software Installation

This section describes how to install the system software found on the CSA8000 & TDS8000 System Rebuild CD that accompanies this product. The instrument ships with the product software installed, so only perform these procedures if

reinstallation becomes necessary.

Description

The product software comprises two parts: H Window 98. Windows 98 comes preinstalled on the instrument. Windows 98

is the operating system on which the user-interface application of this

CSA8000 & TDS8000 Instruments and Sampling Modules

product runs. The System Rebuild CD, which can be used to rebuild the instrument hard drive, includes the Window 98 operating system installation.

If you need to reinstall Windows 98, you may be able to do so without rebuilding the instrument hard drive. See Operating System Reinstallation on page 2–8 for more information.

H User Interface (UI) Application. The UI application complements the

hardware controls of the front panel, allowing complete set up of all instrument features. The System Rebuild CD includes the UI application installation as part of a complete hard drive rebuild.

Software Release Notes

Operating System

Reinstallation

Read the software release notes README.TXT ASCII file if present on the System Rebuild CD before performing any installation procedures. This file contains additional installation and operation information that supercedes other product documentation.

To view the README.TXT file, open the Notepad Windows accessory and open the file on the System Rebuild CD. After installation, you can also read the copy from a directory on the product:

C:\Programs Files\TDSCSA8000\System

Use the following procedure if reinstalling Windows 98 becomes necessary.

NOTE. Only do the reinstall if Windows 98 is missing or corrupted.

There are two possibilities for reinstall: H The instrument can reboot from the hard drive; if so, reinstall windows using

the emergency startup disk and the procedure Windows 98 Reinstall Only on page 2–8.

H The instrument cannot reboot from the hard drive or you do not have an

emergency startup disk available. In either case, you must rebuild your hard drive using the procedure System Hard Drive Rebuild on page 2–9. Any files or programs you have installed will be lost.

2–8

Windows 98 Reinstall Only. If you can reboot from the instrument hard drive and

you have your emergency startup disk, you can reinstall Windows 98 from the hard drive. This procedure is preferred over rebuilding the hard drive, since the rebuild rewrites the entire hard drive.

1. Power off the instrument. Use the On/Standby switch if possible; if not, use

the principle power switch found at the back of the instrument.

CSA8000 & TDS8000 Instruments and Sampling Modules

Installation

2. If a keyboard is not connected to the instrument, connect it.

3. Insert your emergency startup disk in the instrument floppy drive.

4. Power on the instrument. Make sure the principle power switch at the back

of the instrument is set on. Push the On/Standby switch on the front panel.

5. The instrument should now boot from the emergency startup disk and

present you with a selection menu. Use the arrow and enter keys to choose

Start the computer without CDROM support.

6. At the a:\ prompt, type c:. Then type cd windows\options\cabs.

7. Type setup. Follow the instructions on screen.

NOTE. At the a:\ prompt, you can type help at anytime to read a file that may be helpful in getting the Windows 98 operating system up and running.

System Diagnostics

Windows Safe Mode

System Hard Drive Rebuild. If you cannot reboot from the instrument hard drive,

you must rebuild the instrument hard drive. This process will return the hard disk to the its original condition present when the instrument shipped.

Since data and programs you may have installed are lost with this rebuild, you should do the Windows 98 Reinstall Only procedure instead if you can. (See Windows 98 Reinstall Only on page 2–8.)

If you must rebuild the system hard drive, use the System Rebuild CD that shipped with the instrument. Follow the instructions in the booklet found in the CD case.

In case of instrument problems, you may wish to run the system diagnostics. If so, see the procedure Perform the Diagnostics, on page 4–3.

If the instrument is turned off before the operating system boots, or if you’ve installed a third-party product with a driver incompatible with instrument start up, Windows 98 will open in Safe mode. The touchscreen will be inoperable; therefore, you must install the standard-accessory mouse and keyboard to operate the instrument.

When you have finished investigating and removed any barrier to Windows start-up, you can reboot. If the instrument no longer boots to Safe mode, you can remove the keyboard and mouse if desired.

80E00 Electrical Sampling Module Operation

NOTE. These are not comprehensive operating instructions; consult the documentation map on page 2–12 to find other sources of operating instructions.

Each sampling module contains two identical input channels (80E01 has one channel). This section describes channel controls, connectors, and indicators. Figure 2–6 shows the front panel of the sampling module and identifies the buttons, lights, and connectors.

CAUTION. To prevent damage to your sampling module or instrument, do not apply a voltage outside the Maximum Input Voltage (see page 1–12) for your sampling module.

To prevent electrostatic damage to the instrument and sampling modules, follow the precautions described in this manual and the manuals accompanying your instrument.

Operating Instructions

The input signal connectors for each channel let you connect signals that you want to sample. To acquire a signal, connect the signal to the sampling module through the Signal Connector input.

CSA8000 & TDS8000 Instruments and Sampling Modules

2–23

Operating Instructions

Connector Care. Never attach a cable to a sampling-module connector if the cable has a worn or damaged connector because you may damage the sampling-module connector. Use extra care when attaching or removing a cable from the connectors. Turn only the nut, not the cable. When attaching a cable to a sampling-module connector, align the connectors carefully before turning the nut. Use light finger pressure to make this initial connection. Then tighten the nut lightly with a torque wrench.

NOTE. For best repeatability and to prolong connector life, use a torque wrench and tighten the connection to the range of 79–112 N@cm (7–10 lb@in).

If the sampling-module connectors will receive heavy use, such as in a production environment, you should install adapters (such as a Tektronix 015-0549-xx for 3.5 mm connectors) on the sampling module to make connections to the device under test.

Channel Selection

TEKPROBE Connector

TDR On Indicator

Each channel has a SELECT channel button and a yellow channel light. The button operates as follows:

H If the yellow channel light is on, the channel is acquiring a waveform. H If you press the button and the channel is not currently being acquired (for

any channel or math waveform), then the instrument activates (turns on) the channel.

H If you press the button and the channel is currently active as a channel

waveform, then the instrument selects the channel waveform.

H If the channel waveform is already selected when you press the channel

button, the instrument turns the channel off.

The TEKPROBE connector provides support for accessories requiring TEKPROBE SMA support at levels 1 and 2. The connector provides power and control to attached accessories, by the main instrument.

On modules with TDR capability, the red TDR ON light indicates whether the step generator is sending out a step through the signal connector. The main instrument turns this on or off.

80C00 Optical Sampling Module Operation

NOTE. These are not comprehensive operating instructions; consult the documentation map on page 2–12 to find other sources of operating instructions.

NOTE. Proper operation of 80C04 modules requires that the operating–system software installed on the main instrument is version 1.1.0 or greater. To display the version installed, select About TDS/CSA8000 from the Help menu of the main instrument.

CAUTION. To avoid damaging your optical sampling module, handle your optical sampling module carefully at all times and take the following precautions:

Operating Instructions

Attenuating Optical

Signals

Do not drop your sampling optical since damage and misalignment of the photodiode optical assembly can result. Store the sampling optical in a secure location when not in use.

Replace the protective cap on the input connector when the sampling optical is not in use.

To prevent loss of optical power or damage to the optical connectors, keep the connectors clean at all times. Also insure that all connectors and jumpers attached to the inputs are clean prior to insertion.

To keep the optical input power to an appropriate level, it may be necessary to attenuate the optical signal.

CAUTION. To avoid damaging the optical input of the sampling optical, to maintain the levels within performance range, and to avoid clipping, attenuate optical signals to less than 5 mW average power or 10 mW peak power at the wavelength with highest relative responsivity.

80C03 modules can have deteriorated response for signals larger than 200 mW and the vertical response will eventually saturate for levels approaching 1 mW.

The optical input connector uses a universal connector interface (UCI) that allows use of many standard fiber-optic female connector styles. Some of the standard UCI interfaces supported are FC, ST, SC, and DIN. (Refer to a current Tektronix catalog for details.)

Clock Recovery Outputs

Optional clock and data-recovery circuitry provides clock and data outputs; the recovered clock is also internally routed to the main-instrument trigger circuit. The circuitry also provides front-panel outputs: normal and complemented clock, and normal and complemented data (80C02 has data, clock, and 1/16 clock outputs). Use 50 W terminations, provided with your optical sampling module, on unused outputs.

You can disable the internal recovered clock from being used as the main instrument trigger by selecting external or internal clock triggering; select the recovered clock rate without actually selecting recovered clock as the trigger source in order to activate the front-panel clock recovery signals.

CSA8000 & TDS8000 Instruments and Sampling Modules

Theory of Operation

This section describes the electrical operation of the instrument and sampling modules. Figure 9–1 on page 9–1 shows the module interconnections.

Logic Conventions

The instrument contains many digital logic circuits. This manual refers to these circuits with standard logic symbols and terms. Unless otherwise stated, all logic functions are described using the positive-logic convention: the more positive of the two logic levels is the high (1) state, and the more negative level is the low (0) state. Signal states may also be described as “true” meaning their active state or “false” meaning their nonactive state. The specific voltages that constitute a high or low state vary among the electronic devices.

Mainframe Overview

This mainframe overview describes the basic operation of each functional circuit block as shown in Figure 9–1 on page 9–1.

General

Input Signal Path

The instrument control system is a dual Wintel/PowerPC based processor board. The platform features VGA resolution flat-panel display, transparent touch screen and user front-panel with direct access to commonly used scope functions. The instrument is also equipped with a mouse pointing device to facilitate access to more advanced scope functions

A signal enters the instrument through a direct coaxial connection to the input connector on a sampling module, or a real time probe connected to the sampling module channel.

Acquisition System. The acquisition system conditions the input signals, samples them, converts them to digital signals, and controls the acquisition process under direction of the processor system. The acquisition system includes the multisource trigger, acquisition timebase, and acquisition mode generation and control circuitry. The acquisition board is located in the bottom compartment of the instrument and can accommodate four dual-channel sampling Plug-ins, two one-channel optical plug-ins and a trigger/holdoff subsystem. Up to 8 vertical channels are accommodated simultaneously. Channels 1 and 2 are either large or small slots. The presence of an module in one or both large slots displaces the small slot functionality in the leftmost Channel 1 - Channel 2 small slot. The external trigger and all small slot channels feature a Tekprobe Level 2 probe

Theory of Operation

power connector for additional front end signal conditioning functions like high input-impedance real-time probes.

Processor System. The processor system contains a dual Wintel/Power PCC. The basic instrument configuration supports up to eight channels labeled Ch1 through Ch 8, provides two external trigger inputs for direct and prescaled triggering through built–in prescaler and is able to support two optional internal trigger sources associated with the large slot channels mapped onto electrical channels 1 and 2.

Display Panel

Front Panel

Rear Panel

Color LCD display Active-matrix touch panel.

Display System. Text and waveforms are processed by different parts of the display circuitry. The display system sends the text and waveform information to the display panel.

T ouch Panel. The Display board sends information to the processor. Any changes in their settings are reported to the processor system.

The front panel board reads the front-panel switches and knob sensors. Any changes in their settings are reported to the processor system. The front panel board also turns the LEDs on and off and generates the bell signal.

Front-panel menu switches are also read by the PPC processor board. The processor sends any changes in menu selections to the processor system. The ON/STBY switch is one of the menu switches. However, it is not read by the front panel board, but passes through the front panel board to the low voltage power supply.

The hard drive and CD Rom provides access to stored waveform data and to load software to customized your instrument with your measurement needs. The GPIB allows for external control of the instrument.

Low Voltage Power Supply

3–2

You can make hardcopies on the GPIB, RS-232, and Centronics ports. Other ports from the front panel board: PC cardbus x 2, cal adjust lock.

Outputs from the NLX board: SVGA, USB (1), sound, serial (2), parallel, Ethernet, mouse, keyboard.

The low voltage power supply is a switching power converter with active power factor control. It supplies power to all of the circuitry in the instrument.

The principal POWER switch, located on the rear panel, controls all power to the instrument including the Low Voltage Power Supply. The ON/STBY switch,

CSA8000 & TDS8000 Instruments and Sampling Modules

Theory of Operation

located on the front panel, also controls all of the power to the instrument except for part of the circuitry in the Low Voltage Power Supply.

The power supply sends a power fail (~PF) warning to the processor system if the power is going down.

Fans

80E01, 80E02, 80E03 and

Electrical Sampling

Modules

The fan assembly provides forced air cooling for the instrument. The fans are controlled by the PPC processor.

The 80E01, 80E02, and 80E03 and are two-channel, low-noise, 12.5, 20 and 50 GHz, samplers, respectively. The 80E02 sampling module has a 28 ps rise time, the 80E03 17.5 ps and the 80E01, 7 ps.

For the 80E02 and 80E03, a single strobe delivered from the instrument mainframe to both acquisition channels controls the timing of the strobe assertion to both channels. If channel-to-channel deskew is zero, the sampling coincidence between channels is very close. Acquisition deskew function is carried out by making separate acquisitions over individual acquisition windows.

For the 80E01, an individual strobe delivered from the instrument mainframe to the acquisition channel controls the timing of the strobe assertion to the channel. Acquisition deskew function is carried out by moving the strobe timing for the channel to a unique acquisition window.

Each electrical channel features a Tekpobe Level 2 probe power connector for attachment of a real time probe. The control of this probe is a mainframe function.

All module calibration signals are derived from a 2.5 V precision voltage reference internal to the sampling module. Settings derived from this reference are stored in a non-volatile EEPROM in the sampling module, although the responsibility for the execution of these settings is with the mainframe.

For major functional circuit blocks refer to (Figure 9–3).

Theory of Operation

80E04 Electrical

TDR/Sampling Module

The 80E04 TDR/Sampling module is a two-channel, low noise, 17.5 ps rise time sampler. Each channel is also capable of generating its own Time Domain Reflectometry (TDR) step. The 80E04 sampling module risetime is 17.5 ps.

For the 80E04 a single strobe delivered from the instrument mainframe to both acquisition channels controls the timing of the strobe assertion to both channels. If channel-to-channel deskew is zero, the sampling coincidence between channels is very close. Acquisition deskew function is carried out by making separate acquisitions over acquisition windows.

Each electrical channel features a Tekpobe Level 2 probe power connector for attachment of a real time probe. The control of this probe is a mainframe function.

When used in the acquisition mode (that is, with the TDR step generator turned off) each channel functions as a normal sampling input. Both channels are strobed simultaneously from a single strobe generator contained within the sampling module, so time coincidence between the two channels is stable.

In the TDR mode, a fast rise time step is generated internally for each channel and applied to the input signal path for that channel. The acquisition portion of the TDR/sampling module remains functional for monitoring the primary step and its reflected components. The sampling module provides two self- contained TDR channels. The polarity of the output step can be selected independently for each channel. This allows differential or common mode testing of two coupled lines as well as independent testing of isolated lines.

For major functional circuit blocks refer to (Figure 9–4).

CSA8000 & TDS8000 Instruments and Sampling Modules

Theory of Operation

80C0X and 80C0X-CR

Optical Sampling Modules

80C0X and 80C0X-CR optical modules share the same mechanical package and built with a common circuit board. Different functionality within the modules (current and future modules) is achieved by installing different O/E modules, filters and clock recovery boards along with setting the sampler bandwidth as demanded. The key features supported in the module are:

H A one channel, low noise, adjustable bandwidth sampler allowing multiple

bandwidth settings for optimizing noise verses bandwidth demands.

H An amplified or non-amplified O/E converter. H Support for a switch module with a straight through path and two filtered

reference receiver paths between the O/E converter and the sampler.

H An average optical power meter. H Integral clock recovery option with internal plumbing connection to the

trigger, front panel clock and data output.

C communication with the mainframe for identification, control and

H I

calibration/compensation storage.

The “system response” depends on all of the components in the signal path from the front panel to the sampler. Bandwidth and reference receiver responses are calibrated at the factory with a sub-picosecond optical impulse applied to the front panel connector. This insures that all components are included, but also means that components can not be replaced without performing calibration.

Compensation performs a DC transfer curve characterization for each bandwidth/ reference receiver setting. The curve data is stored in the module’s EEPROM and used to generate a look-up table in the mainframe. This data corrects for linearity, gain and offset errors in the sampler.

Reference receivers can be created in any of the following ways:

H A hardware filter inserted between the sampler and O/E. H Adjust the sampler’s bandwidth. H Adjust the O/E response with the sampler set to a higher bandwidth.

The available bandwidth and reference receiver selections, and the method used to set the bandwidth for 80C01, 80C02, and 80C03 optical modules:

The power monitor is a second measure of the photodiode current that is independent of the sampler signal path. Analog circuitry continuously senses the current flowing into the bias side of the photodiode. The signal is amplified by a programmable gain amplifier and input to an 8 bit AD converter. The AD

converter and amplifier are controlled through the I

C interface. Compensation performs two functions in the power meter: First, two offset inputs are adjusted in the amplifier so that the signal stays in range for all of the gain settings. Next,

CSA8000 & TDS8000 Instruments and Sampling Modules

3–5

Theory of Operation

offset is measured for all gain settings and stored so it can be subtracted from the raw measured current. Because the measurements are made through independent paths the power monitor is useful in debugging module/mainframe problems.

The module’s main board only provides power and control bits to the clock recovery board. A small fraction of the input signal is split off to applied to the clock recovery components. The splitter is optical in the 80C01-CR and 80C02-CR, and is electrical in the 80C03-CR. The recovered clock is routed in coaxial cable through the rear connector to the module to the Optical Front End board in the mainframe. The Optical Front End board has a switch that selects which modules clock will be applied to the trigger. The control signal for that switch comes from the optical module.

80C01 Optical Sampling

Module

The 80C01 module supports conformance testing of long wavelength (1100-1650 nm) signals at 622, 2488, and 9953 Mbps as well as general purpose testing up to 20 GHz optical bandwidth. Bandwidth and reference receiver calibration is performed with a sub-picosecond and optical impulse and a fourier transform method.

H OC12: The electrical sampler is adjusted to approximately 7.5 GHz

(–3dB) bandwidth and signal is routed through a hardware filter designed to result in the combined system having an OC12 (STM-4) Reference Receiver response.

H OC48: The electrical sampler is adjusted to 7.5 GHz (–3dB) bandwidth

and signal is routed through a hardware filter designed to result in the combined system having an OC48 (STM-16) Reference Receiver response. These adjustments must be made at the factory.

H OC192: The electrical sampler is adjusted to give the desired response,

and signal is not routed through any filter (signal is sent through the straight-through path). The sampler bandwidth and response is optimized during the calibration such that the combined system will have an OC192 (STM-64) Reference Receiver response.

H 12.5 GHz: The sampler bandwidth and response is set during the

calibration such that the combined system will have an Optical Bandwidth (–6dB) > 12.5 GHz.

3–6

H 20 GHz: The sampler bandwidth and response is set during the

calibration such that the combined system will have an Optical Bandwidth (–6dB) > 20 GHz.

80C02 Optical Sampling

Module

The 80C02 module is optimized for testing of long-wavelength (1100-1650 nm) signals at (9.953 Gbps) SONET OC-192 / SDH STM-64 standards. With its high optical bandwidth (>30 GHz) it is also well suited to general purpose high-performance optical component testing.

H OC192: The electrical sampler is adjusted to give the desired response,

H 12.5 GHz: The sampler bandwidth and response is set during the

calibration such that the combined system will have an Optical Bandwidth (–6dB) > 12.5 GHz.

H 20 GHz: The sampler bandwidth and response is set during the

calibration such that the combined system will have an Optical Bandwidth (–6dB) > 20 GHz.

H 30 GHz: The sampler bandwidth and response is set during the

calibration such that the combined system will have an Optical Bandwidth (–6dB) > 30 GHz.

For major functional circuit blocks refer to (Figure 9–7 on page 9–7).

80C03 Optical Sampling

Module

The 80C03 module supports conformance testing of both short and long bandwidth (700-1650 nm) signals at 1.063, 1.250, and 2.488 Mbps as well as general purpose testing with up to 2.3 GHz optical bandwidth. Its amplified optical to electrical converter design enables the user to examine very low-level optical signals.

H OC48: The electrical sampler is adjusted to approximately 12.5 GHz

(–3dB) bandwidth and signal is not routed through any filter (signal is sent through the straight-through path). The O/E converter is designed by the vendor to match the OC48 reference receiver response curve. The span adjustment provides limited adjustment of the frequency response. It is adjustment at the factory such that the combined system will have during calibration such that the combined system will have an OC48 (STM-64) Reference Receiver response. This mode is synonymous with the 2.3 GHz maximum bandwidth setting.

H FC: The electrical sampler is adjusted and O/E converter span voltage

are the same values as in the OC48 mode. The signal is routed through a hardware filter designed to result in the combined system having an FC1063 (1.0625 Gb/s Fibre Channel) Reference Receiver response.

H GBE: The electrical sampler is adjusted and O/E converter span voltage

are the same values as in the OC48 mode. The signal is routed through a
