The Weinschel 1404WPC is a precision programmable attenuator designed for RF and microwave applications. Here are some general specifications for the Weinschel 1404WPC:

1. Frequency Range: The 1404WPC typically operates within a specific frequency range, such as DC to 18 GHz or another specified range.

2. Attenuation Range: The attenuator provides a selectable attenuation range, typically adjustable in small increments. The range can vary, but it is often between 0 and 70 dB.

3. Attenuation Accuracy: The 1404WPC offers high attenuation accuracy, typically with a specified tolerance or uncertainty. This accuracy can be expressed in dB or as a percentage of the selected attenuation level.

4. Insertion Loss: The device introduces some level of insertion loss when attenuating the signal. The insertion loss is generally low and can vary depending on the frequency and attenuation setting.

5. VSWR: The Voltage Standing Wave Ratio (VSWR) represents the reflected power in the system. The 1404WPC is designed to have a low VSWR to minimize signal reflections.

6. Control Interface: The 1404WPC may have various control interfaces, such as USB, Ethernet, GPIB (General Purpose Interface Bus), or RS-232, allowing for remote or automated control.

Please note that these specifications are general and may vary depending on the specific model or configuration of the Weinschel 1404WPC attenuator. For detailed and accurate information, it is recommended to refer to the product datasheet or contact Weinschel directly for the most up-to-date specifications.
