I/Q Tuning Measurement Description

Single or Multi Measurements

The I/Q Tuning measurement can return either single or averaged measurement results.
• If you set the multi-measurement state OFF then only a single measurement is made at each offset.
• If you set the multi-measurement state ON, and the multi-measurement count number to a value greater
than one, then multiple measurements are made at each offset. The returned results are an average of
these measurements.

Types of Signals I/Q Tuning can Measure

I/Q Tuning measurements can be made on these types of input signals.
• Normal GSM TCH burst without a midamble.
• CW signal.

I/Q Tuning Input Signal Requirements

The I/Q Tuning measurement will complete and meet its measurement accuracy specifications under the
following input signal conditions.
• Input signal level is between -15 dBm and +43 dBm.
• Input signal level is within +3 dB and -10 dB of the expected input level.
• Signal must be within 500 kHz of expected frequency for RF Rise triggering to function.

Trigger Source

The trigger source depends on the type of input signal.
