Beep - Limit Warning
Activates an acoustic alarm when there is a violation of user-defined limits.
Activation applies to all windows. If a warning beep in conjunction with a violation of user-
defined limits is not desired, it can explicitly and exclusively for any window be switched
off in the limits dialog, see
​
chapter 4.4.5, "Limit Monitoring" , on page 110.
Display Update
Selects the display refresh rate.
At very low ambient temperatures, the display becomes sluggish. To improve readability
under these circumstances, you can reduce the display update rate.
"Normal" standard display update rate.
"Slow" preferred setting rate at very low ambient temperatures.
"Frozen"
for interruption-free update of analog outputs, see
​
chapter 4.7.2.3,
"Voltage at the analog outputs" , on page 155. The meter indicates "fro-
zen" in the info line of the results window.

4.7.6 Test measurements
Since the scope of testing is limited, test measurements cannot replace a regular reca-
libration of the sensor.
The "Test..." function offers tests for the internal circuitry of the sensor (selftest 1) as well
as simple tests with applied RF (option R&S
NRP2-B1 required).
