Query Syntax

:MEASure:RESPonse:TDENsity?

Description

For the FlexPLL Response waveform's TDensity measurement, returns the Current value displayed in the results table.

Returns the current value for JTF model waveform's Transition Density measurement. This is the density of a digital signal, which affects the number of error pulses from a PLL's phase detector. A 1010 pattern results in a transition density of 100%, which results in an error pulse in the error signal for every clock cycle. A PRBS pattern has a transition density of 50%, which results, on average, in a pulse in the error signal every two clock cycles. The transition density is sometimes used in a PLL to set the loop bandwidth.

Transition Density can be measured only on a live Response graph but not a Response that is saved in a Response memory.

Measurement Ready?

To confirm that the measurement is ready to read, you can query the measurement's status:

if ('CORR' in Flex.query(':MEASure:TDENsity:STATus?')):
	measurement = Flex.query(':MEASure:TDENsity?')

Common Measurement Child Queries

This command supports the use of the following common measurement queries: :COUNt?, :MAXimum?, :MINimum?, :MEAN?, and :SDEViation?.
