HP8753ES Setup
TS3L301
16-BIT TO 8-BIT SPDT GIGABIT LAN SWITCH
WITH LOW AND FLAT ON-STATE RESISTANCE
SCDS178C – NOVEMBER 2004 – REVISED APRIL 2006
A. C
L
includes probe and jig capacitance.
B. A 50- Ω termination resistor is needed to match the loading of the network analyzer.
Figure 7. Test Circuit for Crosstalk (X
TALK
)
Crosstalk is measured at the output of the nonadjacent ON channel. For example, when V
SEL
= 0 and A
1
is the
input, the output is measured at A
3
. All unused analog input (A) ports are connected to GND, and output (B)
ports are left open.
