7.5.2 The DualPDA Detector Unit The basic version of the 58N81 DualPDA detector unit is configured for the measurement of two velocity components and includes two interference filters for 514.5 nm (green) for the U1 and U2 channels and two 488 nm filters (blue) for the V1 and V2 channels. U1 U2 U3/V2 U1 U2 U3/V2 V1 U1 58N81 Detector Unit U1 U2 U3/V2 V1 W U2 U3/V2 V1 W V1 W FIBER INPUT PMT SIGNAL OUTPUT HIGH VOLTAGE INPUT PMT AUX. POWER Figure 7-59: Back panel of the 58N81 DualPDA Detector Unit. Colour separation For a 3D configuration the 58N82 DualPDA Velocity Extension Kit includes a for 3D colour separator with a 476.5 nm (violet) interference filter for the W channel. 7.5.3 Changing interference filters A small tool is supplied which has to be plugged onto the fiber connector at the backside of the detection unit. This tool allows unscrewing the back part of the filter connector and taking it off from the detection unit. The mounted interference filter can then be unscrewed manually from this back part of the fiber connector and be exchanged by another one. 7.5.4 Configuring the DualPDA system in FiberPDA system Although the four-detector configuration on the DualPDA has advantages in certain applications, it should be pointed out that it is not in general superior for all the applications. There are applications where the sensitivity of the planar PDA has more disadvantages and where a standart three-detector configuration would be more robust. A DualPDA system can therefore be easily converted to a FiberPDA configuration. The conversion of a DualPDA to a FiberPDA comprises four steps: Exchanging the aperture plate. Remove the DualPDA aperture plate (chapter 0) from the DualPDA probe and mount the according FiberPDA aperture plate (Figure 7-43 ) into the DualPDA probe instead. Exchanging the third interference filter in the DualPDA detection box. 7-78 BSA Flow Software: Reference guide CAL. INPUT SHUTTER
Disconnect the receiving fiber V1 from the back panel of the DualPDA detector unit. Exchange the 488nm (blue) interference filter with a 514.5nm (green) in following instructions above (chapter 7.5.3). One extra 514.5nm filter is supplied with every DualPDA detector unit.

Connect the detector unit, receiving fiber and processor The four receiving fibers from the DualPDA probe have to be connected according to the label of the fiber and detector unit connectors. The first three photomultiplier (with the 3 green interference filters) have to be connected to the first three input channels of he processor. The fourth photomultiplier (with the blue interference filter) has to be connected to the fourth input channel of the processor. Select FiberPDA in the BSA flow software. Configure and use the BSA flow application software for a FiberPDA receiving probe. 7.6 A guide to define the PDA optical configuration: Installation The PDA optical configuration is an Excell spreadsheet allowing determining the best scattering angle and the scattering mode to be used for a given application. The PDA optical configuration spreadsheet is avalaible with particle sizing add-on only. and getting started The Excel spreadsheet is automatically installed in C:\Program Files\Dantec Dynamics\BSA Flow Software when the application software is installed. It requires Excell to be installed on the PC. The PDA Optical configuration guide is launched from the Tools menu, in Plug-Ins (see figure Figure 7-61). BSA Flow Software:Reference guide 7-79
