    Option Description 
    1 Frequency counter: If you buy a frequency counter, frequency counter will be installed within the instrument modules, its input connected to the rear panel of the "outer measure input" jack. On the use of this option are described in detail in the manual. 
    ● Frequency Range: 1Hz ~ 100MHz 
    ● Input signal amplitude: 100mVpp ~ 20Vpp 
    2 power amplifier: If you buy a power amplifier, the chassis will install a power amplifier board, which is independent of an instrument component, its input connected to the rear panel of the "amplifier input" jack, output connected to the rear panel of the "2 times the power amplifier output" socket. When used with a test cable, connected to the input signal "amplifier input" port on the rear panel of the "2 times the power amplifier output" that is 2 times the power can be amplified through the signal.Input signal can be a local output A, output B, can also be a signal to other devices. 
    ● Input voltage: 
    Amplifier voltage gain is twice the maximum output amplitude of 22Vpp, so the maximum input rate should be limited to 11Vpp, exceeds the limit, the output signal distortion. 
    ● Frequency range: 
    Power amplifier frequency range 10Hz ~ 150kHz, within this range amplitude flatness better than 3%, sine wave distortion better than 1%, the highest frequency can reach 200kHz. 
    ● Output Power: 
    Amplifier output power expression: P = V2 / R; expression: P is the output power (in W), V rms output amplitude (in Vrms), R is the load resistance (in Ω) maximum output rate of up to 22Vpp (7.8Vrms), minimum load resistance can be as small 2Ω, also the working environment temperature is higher, the higher the output signal frequency, the smaller the required output signal distortion, maximum power output may reach the smaller, Under normal circumstances the maximum output power up to 7W (8Ω) or 1W (50Ω). 
    ● Output Protection: 
    Power amplifier with output short-circuit protection and thermal protection are generally not damaged, but should try to avoid prolonged output short circuit. Frequency, amplitude and load limits as not to be used, especially two parameters can not be used limits, so as not to damage the power amplifier performance. 
    If you buy the RS232, RS232 interface via remote control of the instrumentation.
