This test measures RF Suppression using the IQ Offset measurement from DSSS mode.
The standard uses a different method which requires a repetitive test signal. The test signal then contains "peaks" in the frequency domain, but a null at the center frequency. In the standard, the RF Suppression is measured from the tallest "peak" to the value at the center frequency. By measuring RF Suppression in this manner, the test result depends not only on the RF feedthrough of the carrier, but also on the presence of a test signal and the shape of the transmit filter. By using IQ Offset, we measure the isolated RF feedthrough using a standard 802.11b formatted burst, and we measure correct feedthrough values regardless of the transmit filter shape. The difference between the two values depends on the filter shape, but will likely fall in the range of –9dB for under-filtered situations to –7dB for over-filtered (IQOffset relative to 802.11b method). So, we offer a computed predicted result to compare against tests made using the standard 802.11b test, assuming an under-filtered transmission.
