1 Power Entry model : This is the AC power input terminal. AC input should be within
the range of line voltage
±10%, 50/60Hz.
2 Sweep/Modulation
output : This terminal outputs the modulated waveform that is
synchronous with the Sweep / Modulation function of this
instrument (
±5Vpp Max.)
3 EXT AM Input : This is the BNC connector for amplitude modulation input. The
modulation index is 100% when
±5 is input. The input
resistance is 100k
Ω.
4 GPIB connector : The optional GPIB (IEEE488.2 and SCPI) communication
interface should be plugged here.
5 RS232 connector : This is the port of serial RS232 interface. The DCE and Baud
rate is among 300 ~ 19.2k.
6. Operation
6.1 The Setup of Output Function
Use the two buttons [ ] or [ ] in the FUNCTION column on front panel to select
an output waveform. Available waveforms are arranged in sequence SINE,
SQU, TRIG, RAMP, and ARB (from left to right).
6.2 The Setup of Frequency
n Press [ FREQ ] button.
o Key in the desired value of frequency.
p Select a proper unit-button to specify the value.
Example: To set frequency at 250Hz, press [ FREQ ] first; then key in [ 2 ], [ 5 ], [ 0 ], and press
[ Hz ].
The frequency range of waves:
Sine 0.02Hz
∼ 30MHz
Square 0.02Hz
∼ 30MHz
Triangle 0.1Hz
∼ 100kHz
RAMP 0.1Hz
∼ 100kHz
ARB 42.949600MHz/N, N=8, 10,12,…2 15
6.3 The Setup of Amplitude
n Press [ AMPL ] button.
o Key in the desired value of amplitude.
p Select a proper unit-button to specify the value.
Example: To set amplitude at 5Vpp, press [ AMPL ] first, then key in [ 5 ] and press [ Vpp ].
