Selectable bandwidth! An RF capture device housed in a lightweight and compact-sized enclosure.
The "4420A" can record RF signals from the field and bring the data back for playback, allowing for operation verification of the receiver in the same receiving environment as the field, even in factories and laboratories. It supports frequencies from 450 kHz to 3.3 GHz, with a maximum bandwidth of 54 MHz, and options to select from "1 MHz," "8 MHz," "24 MHz," "40 MHz," and "54 MHz." Compared to conventional products, it has achieved significant miniaturization and weight reduction. 【Features】 ■ The recording/replay unit is housed in a lightweight and compact case. - A separate control PC is required in addition to the main unit. - Data is saved on the main unit's SSD (or an optional external large-capacity HDD). ■ It can be used with a DC +12V power supply by using an optional DC-DC adapter. - An external battery is required separately. ■ It supports frequencies from 450 kHz to 3.3 GHz. - With options, it can also support frequencies from 50 kHz to 30 MHz. *For more details, please refer to the PDF document or feel free to contact us.
