MEAS SYNC

Making Measurements

If You Have Problems with a Measurement

Solution 2 - Midamble Sync

On the MEAS SYNC screen (press to gain access),

•Check the definition of the signal’s burst type (A).

•Check the Burst Sel field (B).

A

B

Check the bit pattern of your measurement

Perform a Data Bits measurement (D). An “M” will display under the bits that are identified as the midamble bits.
