3.2 Input and output connectors
Waveform output (FUNCTION OUT)
50Ω
FUNCTION OUT
±42 Vpeak
Output amp
50Ω
20dB
ATT
Maximum output voltage : 20 Vp-p/open, 10 Vp-p/50 Ω load
Output impedance : 50 Ω, unbalanced
Load impedance: More than 45 Ω
Output off status : Open when output off (can be modified for 50 Ω at output off. Consult
company.)
Ground : Connected to signal ground (floating from chassis)
Avoid shorting the output or applying an external signal. The unit can be damaged.
・Output limiting
If the following voltages are exceeded by the amplitude, DC offset, the OVER lamp flashes and the
output is clipped.
10 V range: Approx. 11 Vp/open
1 V range: Approx. 1.1 Vp/open
・Output connection note
The FUNCTION OUT impedance is 50 Ω. By using coaxial cable with 50 Ω characteristic
impedance for connection to other equipment, amplitude accuracy at high frequency can be improved and
waveform disturbance reduced. In addition, performance deterioration up to maximum frequency can
be prevented by connecting to a terminal having 50 Ω input impedance or terminating the input at 50 Ω.
・Setting and output voltages
The setting voltage display and actual output voltage (load terminal voltage) differ according to the load
resistance.
