The Keysight 86120B—At a Glance
In addition to these measurements, a “power bar” is displayed that shows power
changes like a traditional analog meter. You can see the power bar shown in the fol-
lowing figure of the Keysight 86120B’s display.
C A U T I O N
The input circuitry of the Keysight 86120B can be damaged when total input
power levels 18 dBm. To prevent input damage, this specified level
must not be exceeded.
Print measurement results
You can get hardcopy results of your measurements by connecting a printer to the
rear-panel PARALLEL PRINTER PORT connector.
Program the instrument for automatic measurements
The Keysight 86120B offers an extensive set of GPIB programming commands.
These commands allow you to perform automated measurements on manufacturing
production lines and remote sites.
Chapter 4, “Programming” and Chapter 5, “Com-
mon Commands” provide all the information you’ll need to know in order to pro-
gram the Keysight 86120B.
Display wavelengths as if measured in vacuum or standard air
Although all measurements are made in air, displayed results are corrected for air
dispersion to accurately show wavelength values in vacuum or in “standard air.” To
ensure accurate wavelength measurements, make sure that you enter the elevation
from which you will be making measurements as described in
Chapter 1, “Getting
Started” .
