OPERATION
(7) Press the waveform select switch]) to the
:.:1£
position to obtain sine waves.
Press the switch to
the~·
position for square waves .
• FREQUENCY SELECTION
Set the freq. range switch@ to the desired range, then set the frequency dial@ so that
indicates your frequency.
EXAMPLE: TO SET THE 5KHz.
(1)
Press the freq. range switch@
x
100.
(2)
Set the pointer of the frequency dial to "50" on the mid position.
The frequency thus selected is : 50 x 1 00 =5KHz
• ADJUSTMENT OF OUTPUT VOLT AGE
The output voltage from OUTPUT BNC
®.
be it sine wave or square wave. can be
continuously varied by AMPLITUDE VR @and stepped by attenuator @.
EXAMPLE : TO ADJUST OUTPUT VOLTAGE TO 10 mVrms PROCEED AS FOLLOWS:
(1)
Connect a voltmeter capable of measuring AC 1 Vrms to output BNC.
(2)
Set the attenuator to {0) dB and then adjust amplitude V R until the voltmeter indicates
1
Vrms. A voltage
1
Vrms will appear at output BNC.
(3) Set attenuator to -40dB. The voltage of
1
0 m Vrms appears at OUTPUT BNC .
• SPECIAL FUNCTION (PROGRAMED FREQUENCY)
Programed frequency(400Hz. 1KHz) usable in audio mode, and modulation. in this function,
frequency is continuously output programed frequency without frequency range switch
and variable .
• OUTPUT IMPEDANCE(Zo)
The A0-3001C provides two output of different impedance the values 600.Q or 50.Q
respectively allow on easy adaptation to the different measuring applications.
NOTE
Carefully select the cable used for the output connector
because some cable cause poor frequency characteristics
for sine waveform and poor leading edge characteristics for square waveform.
