1overview

YS2499B Dual Channel Pulse Power Meter（Dual channel waveform microwave power meter）It is a newly upgraded multifunctional dual channel digital pulse peak power meterCapable of measuring pulse signals and continuous wave signals.YS2499B Dual Channel Pulse Power Meter（Dual channel waveform microwave power meter）Built in dual channel system12bit、80MSampling rate: high-speed samplingADCAnd cooperateFPGAThe new generation pulse high-speed signal processing method can accurately reproduce the detection envelope of the measured signal without distortion;YS2499B Dual Channel Pulse Power Meter（Dual channel waveform microwave power meter）ofThe measurement interface display adopts4.3The inch full-color LCD display screen, as the display interface, can accurately restore the waveform of the measured signal.YS2499B Dual Channel Pulse Power Meter（Dual channel waveform microwave power meter）configurationLAN(This feature is not enabled as standard)、USB、RS232Programmable interface, diversified digital communication interface for users to remotely control. The back panel of YS2499B dual channel pulse power meter (dual channel waveform microwave power meter) is also equipped with two additionalBNCThe interface is used forA.BThe detection outputs of two channels can be provided to an oscilloscope for real-time monitoring of the detection envelope of the measured signal.

YS2499B Dual Channel Pulse Power Meter（Dual channel waveform microwave power meter）It can be achieved through external devicesTwo channels measure the incident power separatelyAnd reflected powerThus, corresponding standing wave ratio and reflection system can be obtained, and continuous wave microwave power can also be measured.YS2499B pulse power meter（Dual channel waveform microwave power meter）alsoUsed for standing wave ratio monitoring of various microwave high-power systems.YS2499B pulse power meter（Dual channel waveform microwave power meter）correctThe upgraded product of YS (M) 2498 dual channel pulse RF power meter.Users can choose specific directional couplers to expand the power measurement rangeIt can be measured up to 100MW

two、characteristic

1. Can test the peak power of pulse signals.

2. The power test units dBm and W can be converted to each other.

3. Capable of manual zeroing and power correction.

4. Frequency range: 50MHz-4GHz.(Frequency range can be customized according to requirements, up to 12.4GHz)

5. Power range: 1uW-100mW.(Customizable power range according to requirements)

6. Accuracy: ≤ ±0.5dB

7. Pulse: Width>1 μ s(Customizable according to requirements), repetition frequency50Hz-20kHz.

8. Input interface: N-type.

9. Detection function:

（1) It has a detection output port with a Q9 head. When connected to an oscilloscope, this detection port can display the detection waveform of pulse RF signals on the oscilloscope.

（2) When the input power is ≥ 100mW, the voltage amplitude of the detection output port is ≥ 0.8V.

（3) The detection circuit can fine tune the rising and falling edges, but this function is not reflected outside the device.

10. Work environment:- 10 ℃ -50 ℃.

11. Power supply: mains power.

5Usage

5.1 Precautions

a. Before using this instrument, one should first read the instrument manual and become familiar with the operating methods;

b. This instrument usually works normally after a few minutes of startup. For precision testing, the preheating time is 15 minutes.

5.2 Button Introduction

Ys2499BOn the front panel, there are11 buttons, including 4 function keys, menu key, zero adjustment key, calibration key, and 4 directional keys. There is a power button at the power input interface on the back panel that controls the power on/off.

a. Function keys

Ys2499BshareFour function keys are used to select submenus under each menu page.

b. Menu key

This key is mainly used for switching between menu pages.

c.logarithm/Watt switching

This key is used for logarithms/Watt switching display

d.wave formdata

This key is used for displaying waveforms on the instrument/Switching between data

e. Direction keys

Ys2499B has four directions: up, down, left, and right. The up and down keys are mainly used for numerical addition and subtraction, while the left and right keys are mainly used for cursor movement under submenus.
