Most menus that are used to change channel-specific parameters also include a pair of
channel selector softkeys. These softkeys allow you to direct changes to a single
channel or to all channels at once. In a two-channel Agilent 35670A, the selector
softkeys are [
CHANNEL 1 2
] and [
ALL CHANNELS
]. In a four-channel Agilent 35670A,
they are [
CHANNEL 1 2 3 4
] and [
ALL CHANNELS
]. When you select [
CHANNEL 1 2
](or
[
CHANNEL 1 2 3 4
]), subsequent changes are directed to the highlighted channel. (The
analyzer cycles through the available channels each time you press the this softkey.)
When you select [
ALL CHANNELS
], subsequent changes are directed to all active
channels.
