Right Panel Overview
Right Panel
1. CH2 BNC
It is a BNC (female) connector which nominal impedance is 50Ω
.
The
function of this connector is determined by the work mode of CH2.
2. CH1 BNC
It is a BNC (female) connector which nominal impedance is 50Ω
.
The
function of this connector is determined by the work mode of CH1.
3. EXT.IN Connector
It is a BNC (female) connector for inputting signals for measurement.
Impedance is 100KΩ.
4. TTL_IO Connector
It is a BNC (female) connector for outputting TTL signal synchronized with
CH1 and inputting uplink signal.
1) Under non-uplink status it can output 3.3 Vpp LVTTL signal synchronized
with CH1 and output impedance is no higher than 50Ω.
2) When uplink is enabled and work as slave, the connector works as external
signal input interface and input impedance is more than 100 KΩ. Please refer to
chapter “Synchronization” .
3) Under Measurement function, it is as digital signal input terminal (DC
Coupling).
Note:
Voltage of signal input CANNOT exceed ±20Vac+dc at EXT.IN
Terminal and CANNOT exceed DC5V at TTL_IO Terminal in
case any damage to this instrument.
