Spectrum 1.9 software for the VSA 1200 Vibration Spectrum Analyzers

Datastick Spectrum software is included with all Datastick VSA-series Vibration Spectrum Analyzer systems. Datastick Spectrum runs on the Palm TX handheld computers and makes it easy to collect and analyze vibration waveforms and spectra for condition monitoring, predictive maintenance and routine troubleshooting and machine diagnostics. Reloadable configurations let you change input and display parameters instantly and perform repeatable inspections easily.

The versatile Add Note feature allows you to attach quick memos of on-site observations to your recorded data for export to a PC. Datastick Spectrum is included with the VSA-Series Vibration Spectrum Analyzer hardware module and also includes and smoothly integrates with Datastick Review software for comparing pat measurements, Datastick Manager software for file management on the handheld, and Datastick Reporting System for VSA software for analyzing, trending, and reporting waveform and spectral data on a Windows® desktop PC or laptop computer. See screen shots below.

NEW! Spectrum 2.0 Upgrade includes three new touchscreen tools

for the VSA-1214, VSA-1215 and VSA-1217
Spectrum 2.0 adds three new touchscreen inspection tools to the popup menu on the main screen – for a total of 10 tools. These tools are popular with users who are troubleshooting and want to do fast analysis right at the machine site without going back to the desktop computer.

Segment Overall Tool – Select a band of frequencies and Spectrum shows you the overall vibration in that area, as well as minimum and maximum frequencies for  the band. You can eliminate peaks at frequencies that distort the overall vibration value that you want to see. This is especially helpful for eliminating the high peaks at very low frequencies (called a “ski slope”) – for slow speed equipment.

Segment Overall Peak Tool – Select a peak, and now see the frequencies around the peak highlighted symmetrically. Overall vibration that shows the overall energy in the peak and its sidebands is displayed.

Zoom Autorange Tool – Zoom Autorange makes it easy to distinguish the values in each area. When zooming, the vertical axis of the zoomed region expands or contracts to the highest value in the zoomed region.

Seg Overall
Select the Segment Overall Tool from the popup menu on the main screen. Notice that there are now 10 touchscreen tools.


Seg OV in use
Now you select the frequency range you want to see by dragging the cursor over it. Notice that the peak on the left is not included. This peak would previously have dramatically distorted the actual overall vibration. In addition to overall vibration, the minimum and maximum are shown.



Select the Segment Overall Peak Tool.



Now, as you select the frequency and drag your the stylus, the frequencies to the left and right are symmetrically selected. The overall vibration for the peak frequency and its sidebands is displayed.



Zoom Autorane is now conveniently available from the popup inspection tools on the main screen.



You can now zoom in using the cursor. The vertical axis will now automatically expand or contract to the highest value in the zoomed area, making it much easier to see what is actually occurring.
