What are the measurement uncertainties for the Gain and Noise Figure in the 8614XB OSA Amplifier Test Personality?
Ideally, an EDFA would amplify the input signal by its gain and produce no additional output. However, the EDFA...

FAQ 2003-01-08

What are the wavelength limits of the 86140 optical spectrum analyzer family?
This depends on the mode you are operating. In the normal measurement mode...

FAQ 2003-01-08

If I upgrade my 8614xB optical spectrum analyzer, can I go back?
It is possible to revert to an earlier firmware revision.

FAQ 2003-01-07

Why is air-gapping not recommended for setting optical power levels?
Air gaps are effectively a discontinuity in the optical path.

FAQ 2002-12-02

What is the recommended external printer?
We have tested the HP DeskJet 850C with the OmniBER. This is the printer mentioned in the User's Guide.

FAQ 2002-12-02

Where is the 2 MHz reference output derived from?
The 2 MHz reference output is derived from whichever timing source is being used to clock the transmit data.

FAQ 2002-12-02

What is the OmniBER OTN calibration cycle?
2 years.

FAQ 2002-12-02

Does OmniBER OTN incorporate simultaneous channel monitoring similar to the I&M test set J2127A?
Yes, OmniBER OTN has the same test capability (Signal Wizard).

FAQ 2002-12-02

What data does Frame Capture allow me to collect?
See the table below:

FAQ 2002-12-02

Can I change the OmniBER OTN mainframe from the Front Connectors to Side Connectors option at a later date?
No. The configuration (front or side connectors) must be specified at the time of the initial order.

FAQ 2002-12-02

Does OmniBER OTN have a built in printer?
No, it has a USB port to support an external (PCL3) printer.

FAQ 2002-12-02

What is the A1A2 BOUNDARY function for in the OVERHEAD SEQUENCE page?
This is to test the 6 framing bytes at the A1 A2 boundary in the section overhead.

FAQ 2002-12-02

Is frequency measurement accuracy related to the accuracy of the external clock source?
No. The instrument frequency measurement accuracy is only related to the instrument's internal clock.

FAQ 2002-12-02

How often will the 86140A OSA need to be calibrated to meet ISO 9001 standards?
The 86140A optical spectrum analyzers have a rugged internal design as well as an auto align feature, which means that the optical spectrum analyzers only require calibration once every two years.

FAQ 2002-12-02

Will OmniBER OTN have SCPI-commands compatibility with OmniBER 718/719, J2127A and Spectral BER 10G?
The OmniBER OTN will have a large degree of compatibility with the OmniBER 718/9.

FAQ 2002-12-02

If I connect more than one test instrument to the same signal, and then quickly disconnect and reconnect ...
This is not a realistic test of the instruments' ability to measure service disruption time.

FAQ 2002-12-02

What is the purpose of the (optical) STRESS TEST in the SDH TEST FUNCTION page?
Designed for testing optical clock recovery circuits in the presence of long runs of zero's (after scrambling).

FAQ 2002-12-02

What is the jitter generation noise floor at 10 Gb/s?
The noise floor is .002 UI rms and .02...

FAQ 2002-12-02

Will round trip delay be supported on North American payloads?
Yes, it will be supported at all E-Carrier and T-Carrier rates.

FAQ 2002-12-02

Is it possible to turn the 1310 and 1550 nm EELED's on and off separately if I order option 004?
Yes, it is possible.

FAQ 2002-12-02

What is the average overhead time after a single sweep completed?
Give 1000ms + Sweep Time delay for a single sweep (sweep time is less than 2000ms).

FAQ 2002-12-02

Does the SONET/SDH service disruption measurement come as standard with the OmniBER OTN?
Yes.

FAQ 2002-12-02

What's the difference between the W32 and W34 warranty options?
W34 provides calibration data before and after calibration. W32 provides only post calibration data.

FAQ 2002-12-02

How do I turn off the jitter source after a jitter transfer measurement?
When the jitter transfer measurement completes...

FAQ 2002-12-02
