100MHz VF CONVERTER
N2VF-1H
USER'S MANUAL
#3503 (rev.1） 2016.06.10

1. Feature
N2VF-1H is the 100MHz 2CH V-F Converter that is housed in a NIM-1UNIT case. It has the four-levels
amplification factor switch and the polarity selector switch.
N2VF-1H is easy to be monitored.
i.e., the over-range and polarity are displayed on LED and also outputted as open-collector outputs.
Therefore, V-F conversion is always performed at the optimum conditions.
2. Specification
3. Before using
Before using, please power about 2 hours on for a warm-up.
The frequency deviation becomes large, if warm-up has not been made.

① CH1 Scale over output connector (BNC)
Open collector output. It is isolated from the internal circuit.
Output becomes off if the voltage input is over than the setting.
(normaly close)
② CH2 Scale over output connector (BNC)
Open collector output. It is isolated from the internal circuit.
Output becomes off if the voltage input is over than the setting.
(normaly close)
③ Changeover switch for choosing isolation or common between
NIM GND and the internal circuit GND.
FLOTING: isolation, G.COMMON: common
