溫馨提示
RF-Explorer 原廠資料及下載區位於 https://j3.rf-explorer.com/downloads [ https://j3.rf-explorer.com/downloads ] ,現在已經有簡體中文使用手冊及豐富的說明文件,韌體終身可以更新修正 bugs。Windows / Mac / Linux / Raspberry Pi 等各種平台都有應用軟體支援,並且還有觸控版本!您還可以自行撰寫序列埠程式與主機溝通以便進行自動化控制,無線電波測量儀器普遍價格居高不下,RF-Explorer 系列絕對是您最好的投資!
這系列機種使用簡易、機體強固,請留意下列幾點,可以確保不受電磁波影響導致損害:
- 安裝天線後勿在高電磁場區域內使用,也不要近距離靠近手機(半公尺到一公尺內)。
- 單頻段機種防護耐受力較差,可以考慮加購 Power Limiter 以便防護強烈電磁突波。
- 不使用時請將天線卸除。

Descriptions
The RF Explorer Power Limiter is a custom device designed from scratch to be the perfect protection against strong RF fields.
As you can see on this [ https://j3.rf-explorer.com/40-rfe/article/78-protecting-your-instrument ] note [ https://j3.rf-explorer.com/40-rfe/article/78-protecting-your-instrument ] , [ https://j3.rf-explorer.com/40-rfe/article/78-protecting-your-instrument ] all RF Explorer models have some power ranges for input signal beyond which can be damaged. For most models, the limit is on +5dBm, some others are ok up to +10dBm but only WSUB3G (as well as the RF SMA connector on the right side in a 3G Combo) is protected up to +30dBm.
The new RF Explorer Power Limiter will allow any RF Explorer model to be protected with external signals up to +30dBm (1 Watt), so you get the same level of protection as in the WSUB3G. Furthermore, the power limiter includes additional functionality inside that will otherwise require external devices increasing cost and size:
Power limiter: protection up to +30dBm, for any frequency range between DC-3000Mhz
DC block: You can connect any external DC source up to 16V with no risk of damaging your RF Explorer or interfering in your measurement.
Attenuator: Includes an internal 6dB attenuator to help you extend the range of power signal measurements. 6dB attenuation means only ¼ of the input power is received by the unit. To compensate for this extra attenuation you should indicate OffsetDB:+006 in the ATTENUATOR MENU of your RF Explorer.
The Power Limiter is assembled in a rugged aluminum case and it is very compact when compared to other market offerings, not to mention it includes internal DC block and attenuator which makes it a really small device for what it offers. It is a recommended add-on to all users who may expose their unit to strong external fields.
