	Balance to Ground Measurements
•	LBB Series Longitudinal Balance Bridges LCL and LCTL balance measurements to ground per ITU-T Recommendation O.9 Interface with 50 and 75ohm network analyzers. Balanced impedances 100, 110, 120, 135, 150ohm Models cover 10kHz - 300MHz	•	CMI Series of Common Mode Injectors Apply longitudinal signals to balanced networks in two-port balance tests. Measure common mode rejection of baluns. 50 and 75ohm coax input impedance. Balanced impedances 100, 110, 120, 135, 150ohm Models cover 10kHz -300MHz
•	800 MHz Longitudinal Balance Bridge The NH16455 Longitudinal Balance Bridge has an extended frequency range to 800 MHz. The extended frequency range allows this LBB bridge to measure the degree of unbalance to ground on balanced systems, cables and components such as CAT 6 or CAT 7 cables or patch cords per ITU-T Recommendation 0.9.

	Return Loss Measurements
•	RLB Series Return Loss Bridges for Balanced Networks Interface with 50 and 75ohm network analyzers Measure return loss for balanced impedances 100, 110, 120, 135, 150ohm Models cover 10kHz - 300MHz	•	RLC Series Return Loss Bridges for Coax Networks Interface with 50 and 75ohm network analyzers Measure return loss for coax impedances: 50, 75, 93ohm. Models cover 10kHz - 300MHz
•	RLT Series Return Loss Bridges for Twinax Balanced Networks Interface with 50 and 75ohm network analyzers Measure return loss for balanced impedances 78, 95, 100, 124, 150ohm Models cover 10kHz - 300MHz

	System Noise Susceptibility Measurements
•	BF Series Unbalanced to Highly Balanced Signal Converters with Common Mode Injectors Measure system susceptibility to noise and interference Convert signals from a coax source to a highly balanced output. 50ohm coax input impedance. Balanced outputs 100, 110, 120, 135, 150ohm Models cover 10kHz - 100MHz

	VDSL Measurements
•	ANSI Standard T1.424-2004 Annex F (pages 146-155) Compliance testing of VDSL Network-End Service Splitters.	•	ANSI Standard T1.424-2004 Annex E (pages 135-145) Compliance testing of VDSL Remote (Customer) End Service Splitters.

	C.I.S.P.R 17/IEC 1981 Measurements
•	Balun Transformers for C.I.S.P.R 17/IEC Measurements The NH16434 and NH16435 are optimized for C.I.S.P.R 17/IEC measurements.

	Balanced Impedance Adaptor for Impedance Analyzers and LCR Meters
•	Balanced Impedance Adaptor for Impedance Analyzers and LCR Meters 100Hz to 10MHz To facilitate high-accuracy impedance measurements, inputs to Impedance Analyzers and LCR Meters are configured as four-terminal Kelvin connections. The impedance levels are 50ohm balanced to 50ohm unbalanced. The frequency range is 100Hz to 10MHz. The NH16552 is equivalent to the Agilent 16314A.
