SHF 58214 A
Multi-Channel Amplifier Plug-In

Description
The SHF 58214 A is a two or four channel plug-in intended to amplify the output signal from the 33G
outputs channels of a SHF 12104 A Bit Pattern Generator.
This plug-in module is part of the SHF modular measurement series and needs to be installed in amainframe. In case the plug-in is fitted into a right hand mainframe slot on top of the BPG it can beconnected by short jumper cables (part of the delivery) from the BPGs data ports to the input ports of theamplifier.

FeaturesAll settings are computer controlled and adjustable via the BCC (BERT Control Center) software
package
Adjustable output voltage
Adjustable crossing

Configurations


Option 2C: Two channels (amplifiers) in one plug-in
Option 4C: Four channels (amplifiers) in one plug-in

Specifications – SHF 58214 A
Data Output Specification
All specifications below are only applicable if the SHF 58214 A is driven by and delivered together with a
SHF 12104 A in configuration Dual 33, Quad 33 or Oct 33. Existing SHF 12104 A Bit Pattern Generators
might need to be sent back to SHF for recalibration in order to achieve the below stated minimum output
level.

Application Example
Driving an EA Modulator
Current electro-absorption modulators require a drive voltage of ≤ 3V with an adjustable crossing up to 75 %.
For this application it is recommended to attach an external 6 dB coaxial attenuator to the output of theSHF 58214 A multi-channel amplifier plug-in. This will change the following specifications.
By selecting an attenuator in the control software, it will calibrate the voltage reading to the attenuator’s output.
