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.

Figure 2-9 shows the internal schematic of a single attenuator section.
