    自动调制度测试仪 AUTOMATIC MODULATION METER WAVETEK 4101

    厂家: CT SYSTEMS.INC.

    The Wavetek Model 4101 is a compact,fully automatic modulation meter designed to make rapid and accurate modulation measurements when testing communications transceivers and othe equipment and frequency modulated signals.

    Model 4101 features exceptionally wide coverage of both carrier frequency (1.5 MHz to 2.0 GHz) and level (3 mV to 1 V ) with no use adjustments. The front-panel controls are siple and self-explanatory. Selection of function, meter range, filter, and de-emphasis is made via pushbuttons.

    In addition to providing extreme ease of operation , the compace, lightweight Model 4101 features a rechargeable battery option (six hour operating time), making it an ideal instrument for assessing modulation performance in either the laboratory or the field.

    射频输入

    频率范围: 1.5MHz - 2GHz
    输入电平范围: 
    Specified: 10 mV to 1 V
    Operational: 3 mV to 1 V
    Maximum: 1 Watt ( 7 Vrms)
    输入阻抗: 50 ohms

    调频测量

    调制频率范围: 25 Hz to 50 kHz
    偏差范围: 1,3,5,10, & 100 kHz 
    Measurements of positive and negative deviation and difference can be made.
    精度度( 1 kHz modulation rate):± (2% of FS + 2% of reading + residual FM).
    调频余量:< 20 Hz for carrier frequency up to 100 MHz. Above 100 MHz, increases linearly with frequency (20 Hz / 100 MHz).
    De-Emphasis Selectable 50,75,750 μsec or off. Time constant accuracy = ± 5%.

    调制频率响应 referenced to 1 kHz
    25 Hz –50 kHz FILTER ±5 dB in band
    25 Hz – 15 kHz FILTER ±5 dB in band
    300 Hz – 3 kHz –3dB ±5 dB at band limits.

    调幅测量

    调制频率范围:25 Hz to 50 kHz 
    调幅范围: 10, 30, 50, and 100% 
    Measurements of peak, trough or difference can be made.
    精确度(at 1 kHz modulation rate) ±(2% of FS +2%of reading + residual AM ).
    调幅余量:< 5% with 15 kHz bandwidth.

    信号输出

    中频输出 (Connector Rear-panel BNC)
    频率:~420 kHz
    电平: 100 mV into 50 ohms
    音频输出 (Connector Front-panel BNC)
    电平: .5Vrms at 1 kHz modulation frequency eauals meter FS on any range .
    频率响应: Controlled by selected filter ( see AM and FM frequency response).
    输出阻抗: 600 ohms
    失真度:
    FM < 1% for 50 kHz deviation at 1 kHz modulating frequency. 
    AM < 1% for 80% AM at 1 kHz modulating frequency.
