Screens

Phase/Freq, Data Bits

NOTE

When measuring noisy signals (approx 10° rms), define your entire burst as a User

 

 

Defined Sync Pattern, and select Expected. This will eliminate the problem of bit

 

 

errors causing gross peak phase errors.

3.

Polarity

This field toggles the polarity of the displayed bits.

4.

SyncStatus

This field displays any errors that occurred while trying to synchronize to the

 

 

demodulated data.

5.

Trig Delay

This field sets the time delay between a valid trigger event and the beginning of a

 

 

measurement.

 

 

 

Range

0 to 5000.00 μs.

6.

Trg Timing

This First Bit field displays the position in time of the first useful bit relative to the

 

 

delayed measurement trigger.

Keys: ON/OFF, HI LIMIT, LO LIMIT, REF SET, AVG, Units

 

 

 

The FMErr Count field displays the number of bit differences

 

 

 

detected when comparing the demodulated data bits to the

 

 

 

selected midamble or user defined synchronization pattern

 

 

 

when Sync Mode is set to Midamble. This field will display 0 if

 

 

 

Sync Mode is set to Amplitude.
