Watts. Selecting a Power Head (Sensor) There are a number of Keysight power heads that can be used with the Power Meter in this instrument. Choosing the appropriate power head is a matter of matching the head’s characteristics to the signal to be measured.
Page 94 When there is no signal applied to the power head, the Power Meter reads the NOTE noise level, as shown in the illustration above. This reading is generally below –25 dBm prior to zeroing and will vary. Keysight 53147A/148A/149A Operating and Programming Guide...
Page 95 The instrument is shipped with calibration tables in nonvolatile memory for five of the supported power heads.

Page 284: Overview
Messages Overview The Keysight 53147A/148A/149A provides two types of messages that are displayed on the instrument’s front panel and/or sent over the RS-232 serial interface. The first type is status messages, which are displayed during normal operation. The second type is error messages, which are sent via RS-232 and/or displayed when the instrument detects an error during the Self-Test procedure or during normal operation.
