Capturing the Display
There are two modes of capturing: Freeze and Buffer. The first mode can freeze a single tile, or all tiles simultaneously, and
saves it to memory while other displays and information continue to be live. For this type of capture, frozen information is
lost when the power cycles.
The s econd mode, buffer capture mode, is only available with the WFM7120. Buffer capture captures and stores signal data
for later recall to the instrument or to the USB drive for later analysis. The instrument can be set to buffer capture manually or
using triggers. For procedures for copying the capture buffer to a USB drive, see the Technical Reference on the Product
Documentation CD shipped with your instrument. Both modes are useful for comparing sources or capturing transient events.
NOTE. Both capture freeze and capture buffer information can be downloaded from the instrument Web page.
Capture freeze works in both four-tile and full-screen modes, however, if y ou freeze a trace in 4-tile mode, the image will not
be shown if you go to full-screen mode. The i mage will still be available if you go back to 4-tile mode. Likewise, if you freeze
a waveform image in a tile and then switch the tile to another measurement such as Vector, the frozen waveform image will
be hidden. If you then change the tile back to waveform, the image will reappear.
NOTE. For waveform displays, the captured image is shown in a different color to dis tinguish it from the live image. For all
displays, the instrument continues to log error status in the background while the display is captured.
