3 Short-Range Comms & IoT Mode

3.8 SEM Measurement

View/Blank

Lets you set the state of the two trace variables: Update and Display. The choices

available in this dropdown menu are:

Active Update and Display both ON

View Update OFF; Display ON

Blank Update OFF; Display OFF

Background Update ON, Display OFF

Allows a trace to be blanked and continue to update “in the background”, which

was not possible in the past

In the Swept SA measurement, a trace with DisplayOFF is indicated by a

strikethrough of the type letter in the trace annotation panel in the Measurement

Bar. A trace with UpdateOFF is indicated by dimming the type letter in the trace

annotation panel in the Measurement Bar. In the example below, Traces 3, 4, 5 and

6 have UpdateOFF, and Traces 4 and 6 have DisplayOFF.

See: "More Information" on page 1204

Notes For the commands to control the two variables, Update and Display, see "Trace Update State On/Off"

on page 1202 and "Trace Display State On/Off" on page 1203 below
