CISPR Resolution Bandwidth Shape Accuracy
CISPR Resolution Bandwidth Shape Accuracy
Test Limits
See the test limits in Table 22-31 .
Overview
The CISPR resolution bandwidth shape accuracy is measured for all four of the
CISPR specified resolution bandwidths - 200 Hz, 9 kHz, 120 kHz, and 1 MHz.
The CISPR 16-1-1 standard provides masks that each of these resolution
bandwidths must fall within. This test will verify that the resolution bandwidth
shapes fall within the individual frequency offset points in the standard.
This measurement is performed on RF Input 1 only.
