When the software program starts, the front panel image of the connected DL or WT (control panel) appears on the monitor of your PC. You can control the DL or WT from your PC with the mouse to simulate operations using the front panel keys of the instrument.
Wirepuller is a windows based Yokogawa software program that enables you to control DL Series Oscilloscopes1 or WT1600 Digital Power Meter2 from your PC via Ethernet, USB or GPIB interface. On executing the program, the front panel image of the instruments (DL Series Oscilloscopes¹ or WT1600 Digital Power Meter) connected appears on the monitor of your PC. The control panel resembles the front panel of the actual hardware connected. You can now use a mouse to perform the same operations that you would, as if you were physically present infront of the instrument. This facilitates controlling instruments accross a networked environment (if using Ethernet)
1Excluding DL9000 series and SB series. Please use Xwirepuller for these instruments.

2WT1600 does not support USB interface.
