User GuideEVAL-ADMV4640EVALUATION BOARD HARDWAREThe EVAL-ADMV4640Z comes with an on-board ADMV4640 chip.When evaluating the ADMV4640 device, connect the IF input toan RF signal generator. The EVAL-ADMV4640Z runs on a 5 V dcsupply. Connect the 5 V dc supply to the VCC 5V test point, andthe ground to the GND1 test point.Figure 2 shows the block diagram of the EVAL-ADMV4640Z labbench setup.Figure 2. Lab Bench Setupanalog.comRev.

User GuideEVAL-ADMV4640EVALUATION BOARD SOFTWARE QUICK START PROCEDURESINSTALLING THE ACE SOFTWARE ANDADMV4640 PLUGINS AND DRIVERSThe EVAL-ADMV4640Z software uses the Analog Devices, Inc.,ACE software. Ensure that the ACE software is installed beforesetting up or using the EVAL-ADMV4640Z. For instructions on howto install and use the ACE software, go to www.analog.com/ACE.If the ACE software has already been installed on the PC, ensure that it is the latest version that is shown on the www.analog.com/ACE page.1. Install the latest version of ACE software. In the ACE Setupwindow, ensure that the SDP Drivers, LRF Drivers, and NET4.8 installations are selected (see Figure 3). Then click Install.3. Connect the 5 V clip lead on the power supply to the redVCC 5V test point on the EVAL-ADMV4640Z, and connectthe GND clip lead on the power supply to the black GND1test point. The power supply current limiting must be set toapproximately 500 mA.4. Open the ACE software. The ADMV4640 Board plugin appears in the Attached Hardware section. Double-click theEVAL-ADMV4640Z plugin. The ADMV4640 Board tab opens(see Figure 5).5. Click off the Poll Device button and double-click theADMV4640 button (see Figure 5).Figure 5. ADMV4640 Board TabFigure 3. Drivers to Install with ACE Software2. Open the ACE software and the EVAL-ADMV4640Z pluginappears (see Figure 4).6. The ADMV4640 block diagram appears (see Figure 6).7. Click the Initialization & Optimization button in theADMV4640 block diagram to initialize the device before operation.Figure 6. ADMV4640 Block Diagram in the ACE SoftwareFigure 4. EVAL-ADMV4640Z Plugin WindowCONFIGURING THE BOARDTo set up the EVAL-ADMV4640Z, take the following steps:1. Connect the SDP-S controller board to the J3 connectors on theEVAL-ADMV4640Z.2. Connect the USB cable to the PC and then to the SDP-Scontroller board.analog.com8. To set up the RF, use the following settings and measure theoutput at the IFOUT port: REF IN port: reference frequency 25 MHz, 3 dBm, and dcblock is needed. RF input: RF frequency 12 GHz, 30 dBm. The gain is at minimum attenuation. Note that the chip temperature is higher than 25 C for the reference frequency andRF frequency conditions and there is part to part variation.The gain may be lower than the typical specifications in theADMV4640 data sheet.Rev.
