Power Supply
1. Connect appropriate power supplies to V
CC
, V
EE
,
and GND.
For standard ECL lab setup and test, a split (dual)
power supply is required enabling the 50
W
internal impedance in the oscilloscope to be used
as a termination of the ECL signals (V
TT
= V
CC
– 2.0 V, in split power supply setup, V
TT
is the
system ground, V
CC
is 2.0 V, and V
EE
is –3.0 V or
–1.3 V; see Table 16).
2. Connect a signal generator to the input SMA
connectors. Setup input signal according to the
device data sheet.
3. Connect a test measurement device on the device
output SMA connectors.
NOTE: The test measurement device must contain 50
W
termination.
