HP 70000 series - Auxiliary Indicator Details

Alternate
gain compression
level
if
present, the gain-compression error of signal peaks below
the dashed line does not exceed the gain-compression error
of the mixer-input-level setting (usually about 1 dB for mixer
levels of 0 5 dBm).
Alternate reference level when present, supersedes the top graticule line.
Amplitude oset indicates the amount of oset added to all amplitude
annotation.
Box selects the character for transfer to the title line or the data
line. Also marks character for modication in the data line.
Character set provides character entry into the title line or the data line.
Data line is a scratch pad for composing or displaying custom
functions. Also shows data entry for
NNNNNNNNNNNNNNNNN
TITLE and
NNNNNNNNNNNNNNNNNNNNNNN
COMMAND
functions
.
Detection mode lights when measurements are made with optional detection
modes.
Error message explains the type of error sensed. Refer to Chapter 6 for a

Frequency oset indicates the amount of oset added to frequency
annotation.
Function in progress lights while some functions execute, such as video averaging.
Also lights when some functions change while the sweep is
progressing.
Message area describes the progress of some functions.
Over sweep provides faster sweep times, when autocoupled, by allowing
an additional 2% of frequency error and 2 dB of amplitude
error before displaying the uncalibrated indicator (UNCAL).
