er <amplitude_unit>
This command is used to set the selected window’s measurement units.
For any command which accepts a numeric value in more than one unit
and the power suffix is omitted then the units set by UNIT:POWer are
used.
For the HP E4418B:
• UNIT1:POWer sets the power measurement units for the upper
window. In addition, it also sets the power suffix for any SENSe1
command that requires but omits the power suffix.
• UNIT2:POWer sets the power measurement units for the lower
window.
For the HP E4419B:
• UNIT1:POWer sets the power measurement units for the upper
window. In addition, it also sets the power suffix for any SENSe1
command that requires but omits the power suffix.
• UNIT2:POWer sets the power measurement units for the lower
window. In addition, it also sets the power suffix for any SENSe2
command that requires but omits the power suffix.
For ratio and relative power measurements, if UNIT:POWer is
• W, the measurement units are percentage.
• DBM, the measurement units are dB relative.
