1.1 PRODUCT OVERVIEW

The MFC Switchbox™ can be used to connect a molbox1™ MFC control option or an MFC-CB™ control channel to up to five MFCs, or to one MFC and four MFMs. The rear panel of the MFC Switchbox connects to the molbox1 or MFC-CB via a circular 5-pin connector and a 25-pin DSUB connector. Cables are provided with the switchbox to facilitate these connections. A power cable is also provided. The MFC Switchbox contains its own power supply which allows it to maintain continuous power on all five devices under test (DUTs). The MFC Switchbox provides up to 55 watts of power. This allows it to provide 260 mA per MFC when fully loaded. MFCs typically require a maximum of 200 mA. Therefore, all five ports of the MFC Switchbox can be used simultaneously in most situations. Occasionally, when calibrating older, power hungry MFCs, it may only be feasible to connect four MFCs at a time.

The front panel of the MFC Switchbox has five 25-pin DSUB connectors. These connectors are used to connect the switchbox to the various DUTs.

Current controlled MFCs can only be used on channel 1. When testing MFMs, an MFC can be used for

controlling the flow in the test while taking the measurement data from the currently selected MFM. This controlling MFC must be a voltage based MFC.
