RF powermeter 0-500MHz -80 to 10 dBm of RF power attenuation values can be set

H /// P350
I. Overview:
H //// P350 is a RF power meter, the instrument through the key to complete the operation, the advantages: simple structure, easy to use, stable performance, reliable, high sensitivity and measurement speed and the like.

Second, the application:
RF power measurement;
instrument calibration;

Third, the technical parameters:
No. Item Parameter Unit Remark

8 Storage temperature -40 ~ 65 Celsius
9 size 55 * 45 * 10 mm length X width X height

Fourth, the interface displays and operating instructions:
(1) Unit Description: dBm;
(2) Key Description:
FUN: function keys; MODE: set exchange interface; SEL: from plus key or the minus key self;
4.1, the display of measurement data
Interface display font:
The first line of "RF-POW -80.3 dBm"
The second line "20uV 0nW"
Note: The show signal dBm value, input voltage, input power.
4.2, set the RF power attenuation value
Interface display font:
The first line of "RF Attenuator"
The second line "SUB 000dB"
Key operation:
FUN: function keys; (select plus or minus direction) is displayed as a minus SUB display ADD to add. (Long press FUN key to save the set dB value)
SEL: from plus key or the minus key self;
Note: Different external RF power attenuator, set the corresponding attenuation coefficient reads the correct power parameters.
