NOTES: 1. ALL BNC & SEMIRIGID COAX SHIELD ARE
GROUNDED.
2. ALL RESISTORS 1% (10 Ω = 49.9 Ω).
3. KEEP ALL LEADS AS SHORT AS POSSIBLE
WITH ELECTRICAL LENGTHS L1 = L2 + L3.
4. D.U.T. PLUGS INTO A 16 PIN HIGH
FREQUENCY PIN SOCKET.
5. MONITOR INPUT IMPEDANCE 50 Ω TO GND.
6. SEMIRIGID COAX SHIELD SHOULD BE
CONNECTED AS CLOSE TO THE DEVICE AS
POSSIBLE.
