10MHz Ref
SignalInput

The characteristic impedance of this port is 50Ω. The detectable input
frequency and power range are 10 MHz ± 10 ppm, -3 dBm to +10 dBmrespectively. When there is a 10 MHz external reference signal entering
the port, the VNA’s transmitting signal will be locked into this 10 MHz
external reference signal, otherwise the VNA’s transmitting signal will belocked to the internal 10 MHz reference signal.

SignalOutputThis port can output a 10 MHz reference signal so that it can be used
as a clock by other equipment. The characteristic impedance, output
frequency, and power range are 50 Ω,10 MHz ± 10 ppm, -3 dBm to +10dBm respectively.

Trigger In

When there is an external trigger signal, the VNA will use this external
trigger signal instead of the internal trigger signal.

High threshold voltage: 2.5 V
Input level range: 0 to + 5 V
Pulse width: ≥ 2μs
Polarity: Positive or negative

Trigger Out
