R&S ZVB 

Instrument Construction and Function Description 

1145.1078.82 3.11 

E-1 

Motherboard   

 
The motherboard supplies power to the boards and connects them to the control and data buses. A 
number of RF connections are also routed via the motherboard. 
 
As well as straight connections, a number of circuits are accommodated on the motherboard: 
 
Motherboard controller (MBCON) 
28 V supply 
Preamplifier for the DC measurement inputs 
Supply voltage fuses 
Rear panel interfaces 
Fan control 

 

The 

MBCON

 unit acts as an FSU bus-slave: 

 

•

  to drive the LEDs (instrument front-panel) 

•

   to drive the fan in five stages 

•

  for two temperature sensors on the motherboard 

•

  for an SPI-EEPROM on the motherboard 

•

  Furthermore, the software can detect which device (ZVB4 or ZVB8) is present using the MBCON. 

 

In addition to the voltages delivered by the power supply, +28 V is produced from +12 V on the 
motherboard by means of a boosting switching regulator. This voltage is required to operate the OCXO 
on the reference board when option B4 is fitted. 

 

Each board has its own fuses for the supply voltages. These fuses are soldered into position on the 
board. 

 

All external supply voltages (USB etc.) are protected to prevent shorts.
