Enabling Auxiliary Channels
a full two-port calibration is active, the auxiliary channels can be enabled. To enable
channel 3 or 4, press:
1.
2.
3.
4 .
Once enabled, an auxiliary channel can be made active by pressing twice (for channel
or twice (for channel 4). The active channel is indicated by an amber LED adjacent
to the corresponding channel key. If the LED is steadily on, it indicates that primary channel 1
or 2 is active. If it is flashing, it indicates that channel 3 or 4 is active.
Multiple Channel Displays
The analyzer has the ability to display multiple channels simultaneously,
on separate graticules. Refer to “Display Menu” later in this chapter for
descriptions of the different display capabilities.
Uncoupling Stimulus Values Between Channels
either overlaid or
illustrations and
You can uncouple the stimulus values between the two primary channels by pressing
almost like having the use of a second analyzer. The coupling and uncoupling of the stimulus
values for the two primary channels are independent of the display and marker functions.
Refer to “Channel Stimulus Coupling” later in this chapter for a listing of the stimulus
parameters associated with the coupled channel mode.
Coupled Markers
Measurement markers can have the same stimulus values (coupled) for the two channels, or
they can be uncoupled for independent control in each channel. Refer to “Markers” later in
this chapter for more information about markers.
