Up to 110 MHz (4-Terminal Pair) Balanced/Unbalanced Converters
Description: This balun converts the (unbalanced) 4-
Terminal pair configuration to a (balanced) binding posts
configuration. It is used to measure a balanced device
using an unbalanced measurement instrument.
Applicable Instruments: 4263B, 4268A, 4279A*,
4288A, E4981A (4284A*, 4285A, 4294A, E4980A)**
* denotes the instrument is obsolete.
** applicable in a limited frequency range.
Frequency: 100 Hz to 10 MHz
Nominal Characteristic Impedance:
Unbalanced Side: 50 Ω
Balanced Side: 50 Ω
Insertion Loss: ≤1.0 dB (@ 23°C±5°C, 100 kHz)
Frequency Response: ≤ ±1.0 dB (@ 23°C±5°C, 100 kHz)
specified @ 23°C±5°C
Operating Temperature: 0°C to 55°C
DUT Size: Terminal spacing of balanced side: 14 mm
Compensation and Measurement: Open, short and
load compensations at the measurement terminals of the
balun are recommended before measurement. Short com-
pensation is performed by shorting the binding posts
together with the shorting plate. Load compensation is
performed by using the 50 Ω load resistor. After perform-
ing open, short and load compensations, the DUT is
connected to the binding posts of the balun.
Necessary Accessories:
The 50 Ω load resistor, the shorting plate and the opera-
tion and service manual are not furnished as standard.
The parts should be ordered separately. The operation
and service manual is downloadable from the Agilent
website (www.agilent.com). Search the web using the
keyword “16314A”.
Note: Agilent also provides following baluns for network
analyzers: 16315-60011, 16316A, 16317A
