Support – RF Modules & Instruments
In digital high speed test and measurement, a perfect clock signal is crucial for the generation of low jitter reference test signals. A SHF Synthesized Signal Generator (Synthesizer) used as a clock source can operate over several decades of frequency and is an essential part of any high speed test and measurement environment.
The ability to vary, in a controlled manner, the level and nature of the clock jitter and transfer it to the signal is a key exercise in many R&D as well as production testing. For such stressed test environment, SHF offers a very broad band low jitter clock source, with jitter injection feature, operating over three decades of frequencies from 625 MHz to 67 GHz.
In setups with digital high speed modules and instruments, the clock distribution is always challenging as some parts require a full-clock, others a half-clock, and some even a lower fraction clock signal. Our clock distribution, frequency dividers and frequency doublers are designed to facilitate such a complex test set ups requiring a range of clock signals.
Our filter offer the crucial benefit of improving the quality of a heavily degraded signal after transmission, e.g. for BER measurements. Equalizing operation has been verified for signals up to 60 GBaud PAM4 and 80 Gbps NRZ. Attenuation can be adjusted within a range of 6 to 28 dB with our adjustable attenuator.
With our analog switches, routing between different high-speed clock, NRZ or PAM signal lines can be accommodated easily and fully automated.
Application and Tutorial Notes
- Jitter Injection using the Multi- Channel BPG
This note presents the setup to allow injection of jitter using a SHF Bit Pattern Generator. It demonstrates that SHF BPG’s are jitter transparent, i.e. it correctly transfer jitter from the clock to the data output signal. This enables jitter tolerance tests as required by many telecommunication standards such as 100G Ethernet and 40 GBit/s OTN.
- Jitter Analysis using SHF 10000 Series BERT Equipment
A short description of jitter and a tour of the SHF software used for the measurements. Includes an outline of the theory involved.
SHF Control Center (SCC)
All parts in our current product range of RF & Microwave Modules and Instruments which are controlled by a software running on an external PC require the SCC to operate (e.g. the SHF 78124 A synthesizer). Some obsolete parts of older vintage, however, may require the BCC.
This SHF software is free of charge for the lifetime of your device. The most current version can be downloaded here.
