7. If this is the first time you are upgrading the sensor’s firmware, the power sensor upgrade driver must be installed. In this case, the Windows Found New Hardware wizard automatically starts so the driver can be installed before the firmware upgrade can continue. If the upgrade driver has already been installed, go to Step 9 to continue firmware installation.
8. The power sensor upgrade driver installation is similar to the power sensor driver installation detailed in Installing Power Sensor Drivers. During the upgrade driver installation, Windows will ask for the path to the driver file to install mchpusb.sys (mchpusb64.sys for 64-bit systems). During this step, browse to the program installation directory:
C:\Program Files (x86)\Anritsu\PowerXpert\Drivers
Select the file and complete the upgrade driver installation.
Windows Locate File Dialog
9. If the upgrade driver is installed, click OK (Figure: Continuing with Firmware Update) to continue with the firmware upgrade. The Firmware Upgrade Application shown in Figure: Firmware Upgrade Application appears.
