HP350
I. Overview:
The HP350 is a radio frequency power meter. The meter is operated by keys. The advantages are simple structure, convenient use, stable performance, reliability, high sensitivity and fast measurement speed.
Application:
● RF power measurement;
● Instrument calibration;

Interface display and operation instructions:
(1) Unit description: dBm;
(2) Button description:
FUN: Function key; MODE: Change interface; SEL: Increment or decrement key;
4.1 Display measurement data
Interface display font:
The first line "RF-POW -80.3 dBm"
The second line "20uV 0nW"
Note: The signal dBm value, input voltage value, and input power are displayed separately.
4.2.Set the RF power attenuation value
Interface display font:
First line "RF Attenuator"
The second line "SUB 000dB"
Key operation:
FUN: Function key; (Select the direction of addition and subtraction) Display SUB for subtraction and ADD for addition. (Press and hold the FUN key to save the set dB value)
SEL: Increment or decrement key;
Note: Externally connected different RF power attenuators, set the corresponding attenuation coefficient and read out the correct power parameters.
