Key Descriptions
CHAN UP Moves the center frequency of the spectrum analyzer
higher in frequency by one channel spacing.
Front-panel key access: MEAS/USER
CHANNEL BANDWDTH Allows you to set the channel bandwidth for an
adjacent channel power (ACP) measurement. Changing
the channel bandwidth will affect the channel power
bandwidth setting (CHPWR BW [ ]). The channel
bandwidth can be adjusted using the data keys, the
step keys, or the knob.
Front-panel key access:
MEAS/USER
CHANNEL PWR MENU Accesses the channel power menu of functions
which includes CHANNEL POWER, MKR MEAN
→CF, MKR∆→CHPWR BW, and CHPWR BW [ ].
Front-panel key access:
MEAS/USER
CHANNEL SPACING Allows you to set the spacing between transmitted
signals for an adjacent channel power (ACP)
measurement. CHANNEL SPACING can be adjusted
using the data keys, the step keys, or the knob.
Front-panel key access:
MEAS/USER
CHPWR BW[ ] Allows you to set the channel power bandwidth. This is
the frequency span over which the channel power is
computed. It can be adjusted using the data keys, the
step keys, or the knob. The CHAN PWR OVER BW
softkey uses this bandwidth for its calculation of
channel power.
Changing this parameter does not change the channel
bandwidth parameter in the ACP setup menu.
However, if the channel bandwidth is changed, this
parameter is also updated.
Front-panel key access:
MEAS/USER
CHAR SET 1 2 Selects one of two character sets. Character set 1
contains uppercase letters, numbers,andmiscellaneous
characters. Character set 2 contains lowercase letters
and miscellaneous characters.
Front-panel key access:
DISPLAY
CLEAR WRITE A Clears trace A and sets it to accept and display new
input-signal data continuously.
Front-panel key access: TRACE
CNV LOSS VS FREQ Displays the stored conversion loss for a specific
frequency in the current external mixing band.
