Figure 2-14 Millimeter-Wave Controller
NOTE The illustration above shows the front panel of the controller as it appears in
systems with Option 005 (.045 MHz to 2 GHz range added). If the system
does not have Option 005, the four “RF Input” connectors (a1, b1, a2, and
b2) will be omitted.
LEDs Four LEDs are used as indicators on the front panel:
LINE Lights to indicate that line power to the controller is ON.
ACTIVE Lights to indicate that this is the active test set (useful in
distinguishing among multiple test sets tied to the same
analyzer).
a1 This LED, located at the upper left of the S-parameter
diagram, is lit when the RF source is switched to Port 1.
a2 This LED, located at the lower right of the S-parameter
diagram, is lit when the RF source is switched to Port 2.
