Capture Buttons

The capture buttons in the Force Monitor window allow you to collect data for use with the NanoScope Analysis off-line analysis software.

1. Start to collect a ScanAsyst/Peak Force Tapping image.
2. When you are in a region of interest, click the Capture Line button, shown in Figure 1, to capture a scan line.

3. The High Speed Data Capture window, shown in Figure 2, will open and the Status will change when the data has been captured. Upload Data to the PC when the capture is complete. When Capture Line is used this way, the off-line NanoScope Analysis software will correctly associate the capture line of the high speed data capture with the line in the image.

Figure 2: High speed data capture is complete. However, the data is not immediately transferred to the PC.

4. Click the Upload Data button to transfer the captured data to the computer. While the data transfer process takes place, the scan data will look corrupted because the DSP time is shared between PeakForce QNM properties computation and data transfer.

PeakForce Capture

	Clicking the Enable PeakForce Capture icon enables the:
	Capture with PeakForce Capture and
	Capture Continuous with PeakForce Capture functions to capture an image (of Channel 1) as well as a force curve at every pixel.
	These files may be opened in NanoScope Analysis. The PeakForce Capture function has several restrictions: Channel 1 determines the Direction determines which force curve direction will be captured. The Channel 1 Data Type must not be Off. The Aspect Ratio must be 1.0. The number of Samples/Line must equal the number of Lines. The Scan Rate must not be too high. NOTE: A warning will be displayed and the Enable PeakForce Capture function will be turned off if any of these conditions have been violated. Reconfigure the appropriate parameter before clicking Enable PeakForce Capture.
