2. Wide Dynamic Range: This receiver has a wide dynamic range, which allows it to handle signals of various levels without distortion. This is beneficial for applications that require measuring signals with a large amplitude range.
3. High Stability: The 1701a NEMs Clarke Receiver has a high stability, which means that it maintains its performance over time and temperature changes. This is essential in applications where consistent and reliable measurements are required.
4. Low Noise: The receiver has a low noise level, which reduces the probability of false readings due to background noise. This is beneficial for applications where signal-to-noise ratio is a critical factor.
Cons of buying 1701a NEMs Clarke Receiver:1. High Cost: The 1701a NEMs Clarke Receiver is relatively expensive compared to other receivers in the market. This may be a significant constraint for those with a limited budget.
2. Complexity: The receiver is quite complex and requires specialized knowledge to operate and maintain. This may pose a challenge for users who are not familiar with the device's operation.
3. Limited Availability: The 1701a NEMs Clarke Receiver is not widely available in the market, making it challenging to find replacement parts or technical support.
Conclusion:The 1701a NEMs Clarke Receiver is an excellent choice for applications that require high sensitivity, wide dynamic range, and low noise levels. Its high stability makes it suitable for applications that require consistent and reliable measurements. However, its high cost, complexity, and limited availability may be significant drawbacks for some users. If the benefits outweigh the drawbacks and the user has the technical expertise to operate and maintain the device, then the 1701a NEMs Clarke Receiver is a recommended purchase. If not, other less expensive and more readily available receivers may be a better option.
Here I have a vintage Nems Clarke 1701A special purpose receiver signal level micro volts and micro amperes. It was working before storing but cannot test now so have to sell as is for parts or not. Unit powers on and the dials adjust.
This receiver has some weight to it so that explains the shipping cost. There are obvious scratches and scuffs on body blemishes throughout. The gain makes volume louder white noise while other spins and adjust number dial. Please view pictures before placing bid and ask any questions.
Nothing seems broken and dial lights up.
