5.23 Power Amplifier (Option)
If user selects power amplifier, a power amplifier board will be supplied in the package,
‘Amplifier In’ in rear panel is input connector of power amplifier and ‘Amplifier Out’ is
output connector of power amplifier.
Connect the input signal to ‘Amplifier In’ connector, then amplified signal can be obtained
at the connector of ‘Amplifier Out’. The input signal can be the output signal of this
instrument or other device’s.
5.23.1 Input Waveform
Sine. For other waveforms, the distortion will be greater.
5.23.2 Input voltage
The multiple of the power amplifier is double and the maximum output amplitude is
10Vrms. So the maximum input amplitude should be limited within 5Vrms. The output
signal will be distorted beyond the limitation.
5.23.3 Frequency range
The frequency range of the power amplifier is 1Hz to 150kHz. Within the range, the
distortion of Sine is better than 1％ and the maximum frequency can reach to 200kHz.
5.26.4 Output power
The expression of power for the power amplifier is
P = V
2
/ R
Where, P is the output power(the unit is W), V is the output virtual amplitude value (the
unit is Vrms), R is the load resistance（the unit is Ω）.
The maximum output amplitude can reach 10Vrms and the minimum load resistance can
be 2Ω. Besides, the higher the temperature of the working environment, the larger is the
frequency of the output signal and the greater the distortion of the output signal. Usually,
the maximum output power can reach 8W (8Ω) or 2W (50Ω).
