SHF 58215 A
Multi-Channel AmplifierDescription
The SHF 58215 A is a plug-in intended to amplify the output signals from the 33G output channels of aSHF 12103/4 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 side mainframe slot on top of the BPG it can beconnected by short jumper cables from the BPGs data ports to the input ports of the amplifier.

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

Configurations
Option DC Adjust: Output offset voltage can be varied by software

Specifications
Data Output Specification
All specifications below are only applicable if the SHF 58215 A is driven by and delivered together with aSHF 12103/4 A in configuration Dual 33, Quad 33 or Oct 33. For existing SHF 12103/4 A Bit Pattern
Generators the Amplifier Plug-In needs to be calibrated together with the BPG.

Typical Output Waveforms
Data Output Signals @ 33 Gbps
All measurements had been performed by using a SHF 12104 A Bit Pattern Generator in Config Quad 33,
an Agilent 86100C DCA with Precision Time Base Module (86107A) and a 70 GHz Sampling Head(86118A) directly connected to the output of the SHF 58215 A.

Output Offset Voltage
The output offset voltage is calibrated from into a 50 Ohm load. If the output load resistance varies, theoffset voltage of the output port varies with the internal DC-resistance of ~4 Ohm.
