• Determines the input impedance.

You can select 10 kohm or 50 ohm as the input imped-

ance. For 50 ohm, you can specify the termination

voltage.

• Makes the DC routes.

The specified input pin is connected to the specified

trigger pin. Hence, you can perform DC measurement

at the input pin by using the Pin PMU if you wire the

digital channel to the trigger pin on the DUT board.

When the DC route is made, the DC route is discon-

nected from other routes.

• Makes the loop back routes.

Each input block has an input pin and a loop back pin.

The input pin can be routed to the loop back pin. When

a loop back route is made, the loop back route is

disconnected from other routes. Hence, you can make

multiple loop back routes, or also make a loop back

route and another route (input route or DC route)

using other pins at the same time.

The loop back route is designed so that its line imped-

ance becomes exactly 50 ohm. As a result, the band

width of the loop back route extends up to 700 MHz

(typical value). Hence, by using the loop back route,

you can make a route that has better performance than

using additional user relays on the DUT board.

Center Block

The center block has the following functions:

1 2 ... 234 235 236 237 238 239 240 241 242 243 244 ... 284 285
