Upgraded ZYE660-M1 Portable 9kHz - 6GHz 7Bit RF Digital Programmable Adjustable Attenuator Module PE43711 Built-in 500mA Battery

Description:
- Compact and portable, weighing only 24g.
- Excellent performance indicators, with a 6GHz insertion loss of only 3.2dB and all gear return losses better than 15dB. It can still work up to 10GHz and can meet high demand scenarios such as ADC acquisition. This is precisely because its excellent standing wave performance results in very small errors when switching attenuation gears at different input powers.
- Charging for two minutes and working for a whole day, deeply optimized power consumption as low as 0.5mA.
- Ultra long battery life, up to 2 months. Using Type-C charging, it can be fully charged in two hours, anytime, anywhere, and can be used immediately without the constraints of cables, and there will be no power ripple or stray interference affecting experimental judgment.
- Selecting high PSRR and low-noise LDO: Using a high cost SGM2211 power IC, the power noise suppression can reach 100dB, and up to 9 different specifications of capacitors such as three terminal capacitors are used for filtering.
- Onboard eight digit dip switch, with the first digit set to OFF (parallel control), allows for precise control of 0.25dB, 0.5dB, 1dB, 2dB, 4dB, 8dB, and 16dB levels by setting the attenuation to the last seven digits. Reserved serial SPI control pins are available, and complex attenuation operations can be performed in real-time through the program when the first digit is set to ON.
- Upgraded high-quality connectors, smooth and durable without damaging cables.

Functions and Features:
- Power on/off: the dip switch (EN) is used, and the green indicator light is on to indicate that the equipment has been turned on and is in working condition.
- Flexible control: Eight digit dip switch design, with the first digit controlling serial/parallel mode (OFF for parallel, ON for serial).
- Accurate adjustment: The last seven dip switches control 0.25dB, 0.5dB, 1dB, 2dB, 4dB, 8dB, and 16dB in parallel, allowing for precise setting of attenuation to 31.75dB.

Charging and Power Management:
- Fast charging: using Type-C interface, onboard high-quality charging management IC, charging for two minutes, working for a whole day. It only takes two hours to be fully charged.
- Charging indicator: the red indicator lights up during the charging process and turns green when fully charged.
- Low battery detection: pressing the CHK button and the red indicator turning on indicates that the battery is too low. It is necessary to charge it in a timely manner to avoid interrupting the experiment.
