Connections; Sma Input (Measurement Of External Signals) - Aaronia NF-5030S Manual

12.0 SMA input (measurement of external signals)

The highly sensitive, ultra low-noise input of SPECTRAN (depending on model
down to 0.74nV/ Hz) has specifically been designed for measurement of extre-
mely weak signals, thus the maximum allowable input voltage is very small. The
maximum input voltage is 200nV to 200mV (0.2V) with a frequency of max.
30MHz (if the SPECTRAN is equipped with this option).
WARNING: Be sure not to overload the input! The maximum allowable voltage
is just 200mV (0.2V). Voltages more than 10V can destroy SPECTRAN's highly
sensitive amplifier circuitry!
You can expand the measurement range with our optional Differential
Probe up to 240V! The probe also protects the input from to high voltage (up to
1500V). The probe is a "must have" if you want to measure DSL lines etc.

Starting with the NF-3020, an SMA input is available.
Here, you can connect arbitrary external sensors, like
large, highly sensitive coils, specialized antennas or taps
and similar devices. The incoming signal strength is then
shown in volts.
This additional input allows a wide range of additional
applications and converts SPECTRAN into a true all-
round instrument. To activate the SMA input, simply press
the key 6 and select the analog sensor (the
play reads "ANALOG").
