3.7 ACP Measurement

Notes If :INIT:CONT is ON, then a new continuous measurement will start immediately, with sweep (data

acquisition) occurring once the trigger condition has been met

If :INIT:CONT is OFF, then :INIT:IMM is used to start a single measurement, with sweep (data

acquisition) occurring once the trigger condition has been met

Dependencies For continuous measurement, :ABORt is equivalent to the Restart key

Not all measurements support this command

Status Bits/OPC

dependencies

The STATus:OPERation register bits 0 through 8 are cleared , except bit 6 (Waiting for Periodic

Sync). Initiating a measurement and Waiting for Periodic Sync could be asynchronous

The STATus:QUEStionable register bit 9 (INTegrity sum) is cleared

Since all the bits that feed into OPC are cleared by :ABORt, the Abort command will cause the *OPC

query to return true

Sweep Time Annotation (Remote Query Only)

Returns the Sweep Time Annotation value. Available only on non-sweeping

hardware.

This value is also displayed in the result trace window.

The value returned is the estimated turnaround time of each measurement cycle, in

seconds. The turnaround time is the sum of the signal acquisition time, FFT time,

and other overhead time, to complete the entire span of each measurement cycle.

Remote Command

[:SENSe]:<meas>:SWEep:ETIMe?

<meas> is the identifier for the current measurement; any one of CHPower-

|ACPower|OBWidth|MONitor

Example Channel Power measurement

:CHP:SWE:ETIMe?

Dependencies Available only on non-sweeping hardware

Preset Automatically calculated

3.7.14.2 Sweep Config

Accesses controls that enable you to configure the Sweep and Control functions of

the instrument.

Sweep Time Rules

Switches the instrument between NORMal and ACCuracy sweep states.

Setting Auto Sweep Time to ACCuracy results in slower sweep times, usually about

three times as long, but yields better amplitude accuracy for CW signals. The
