Connecting Field Wiring
Figure 2-8 shows the internal switch diagram for the various HP single-pole, multi-throw switches. All switches are shown in the "OPEN" position. To minimize loss at high frequencies, use the following guidelines when making connections.
∙For frequencies up to 18 GHz, use a good quality flexible type cable and SMA connectors.
∙For frequencies >18 GHz, use semi-rigid type cable and APC 3.5 connectors.
