"Auto Narrow"
Automatically applies the most suitable narrowband preselection fil-
ters in a measurement, depending on the bandwidth you have
selected.
For measurement frequencies up to 30
MHz, the connected instru-
ment uses combinations of lowpass and highpass filters. For higher
frequencies, the connected instrument uses bandpass filters.
Available with the optional preselector.
"Manual"
Applies the filter settings you have defined manually.
Remote command:
10 dB Minimum Attenuation
Turns the availability of attenuation levels of less than 10
dB on and off.
When you turn on this feature, the attenuation is always at least 10
dB. This minimum
attenuation protects the input mixer and avoids accidental setting of 0
dB, especially if
you measure EUTs with high RFI voltage.
When you turn it off, you can also select attenuation levels of less than 10
dB.
The setting applies to a manual selection of the attenuation as well as the automatic
selection of the attenuation.
Remote command:
INPut<ip>:ATTenuation:PROTection:RESet

I/Q File Input

Loading a file via drag&drop
You can load a file simply by selecting it in a file explorer and dragging it to the
R&S
VSE software. Drop it into the "Measurement Group Setup" window or the chan-
nel bar for any channel. The channel is automatically configured for file input, if neces-
sary. If the file contains all essential information, the file input is immediately displayed
in the channel. Otherwise, the "Recall I/Q Recording" dialog box is opened for the
selected file so you can enter the missing information.
If the file contains data from multiple channels (e.g. from LTE measurements), it can be
loaded to individual input sources, if the application supports them.
The "Input Source" settings defined in the "Input" dialog box are identical to those con-
figured for a specific channel in the "Measurement Group Setup" window.
