Setting Measurement Limits; Table 1-2 Range Of Values For Limits - Keysight Technologies U2040 X-Series Programming Manual

Setting Measurement Limits

You can configure the U2040 X-Series to detect when a measurement is outside of a
predefined upper and/or lower limit value. Limits can be applied to power, ratio, or
difference measurements.
Setting limits
The U2040 X-Series can be configured to verify the power being measured against an
upper and/or lower limit value. The range of values that can be set for lower and upper
limits is –150.00 dBm to +230.00 dBm. The default upper limit is +90.00 dBm and the
default lower limit is –90.00 dBm.

Figure 1-5
The range of values that can be set for the upper and lower limits and the default values
depend on the measurement units in the current measurement line. Refer to Table 1-2.
