EMProbe: 1,218 H-field probes
Used to assist high-density board designers to use off-the-shelf hand-held probes and visualize the root causes of potential EMC and EMI problems during pre and post-EMC compliance testing.
Spectral scan, spatial scan, peak-hold, continuous scanning, spectral and spatial comparison, scripting, limit lines, report generation, and notes.
Spatial scan time:
Continuous real-time for the entire scan area (1,218 probes activated) when Level 1 is selected: 5 sec.
Selected area 2.25 cm x 2.25 cm, 9 probes activated.
Level 1: <0.5 sec. | Level 2: 4 sec. | Level 3: 9 sec. | Level 4: 21 sec. | Level 5: 55 sec. | Level 6: 2 min 35 sec. | Level 7: 7 min 23 sec. | Level 8: 24 min 00 sec.
Spectral scan time:
11 seconds for L 10 cm x W 10 cm (L 4” x W 4”, 178 probes activated) from 10 MHz span to 110 MHz and 122 kHz RBW. Scanning area, span, and RBW are user selectable within spectrum analyzer specifications

New Feature ReleaseEnvelope scanning is a major new feature added to the EMViewer software using the EMProbe.
Envelope scanning enables the engineer to define the DUT’s 3D “envelope” by setting the probe height for each scanning point, enabling close scanning that allows the probe to go between individual components. The height definitions are saved to the project file after the first calibration, allowing quick and seamless repeatable scans.
This feature is only available when using the EMViewer with the EMProbe Robotic Arm.
