Page 3: Unpacking
Unpacking When you get a new MHS-5200A Series dual-channel DDS signal generator, it is recommended that you follow these steps to inspect the instrument. 1. Check for transportation damage to the shipping box and packing ma- terials. If there is serious damage, keep them until the machine and accessories have passed the acceptance test. -
Page 4: Model Description
Model description This series of instruments includes four models, differentiated by the maxi- mum frequency of the output sine wave: MHS-5200-06M sinusoidal signals at frequencies up to 6MHz MHS-5200-12M sinusoidal signals at frequencies up to 12MHz MHS-5200-20M sinusoidal signals at frequencies up to 20MHz MHS-5200-25M sinusoidal signals at frequencies up to 25MHz Instrument characteristics •... - Page 5 • All parametric EQ calibration can be performed by internal procedures; • Powerful communications features. Completely open communications protocol allows development of third-party applications • When connected to the PC, the computer can be used to control the instrument. The user can edit arbitrary output waveforms, and down- load it to the instrument •...

Page 11: Selecting Ch1 Waveform
The primary functions, signal waveform and amplitude (Sec. 4.2.1 and 4.2.2), have their own key selectors; other functions are selected by moving through the menu selections by the PgUp and PgDn keys, in the following ✗ ✔ order: WAVE → AMPL → OFFS → DUTY → PHASE → TRACE → FREQ-UNIT →... -
Page 12: Setting Ch1 Voltage Offset
In the default range setting function mode, the maximum amplitude is 15V, and the minimum amplitude is 0.15V; the incremental step value is 0.01V (10mV). The -20dB output attenuator may be selected by pressing the button. With attenuation, the output signal has a maximum value of 1.500V, the minimum value of 0.015V, and the minimum step is 0.001V (1mV). -
Page 13: Setting The Display Unit Of Frequency
4.2.7 Setting the display unit of frequency Change the mode to adjust the frequency units of the display, and then select the frequency units of Hz, kHz, or MHz. 4.2.8 Tracking function Tracking function is used to synchronize the frequency of CH2 to CH1. The amplitude and duty cycle can also be tracked. -
Page 14: Measurement Function
4.2.10 Measurement function Several parameters of the input signal can be measured. • Choose the measurement mode selection, and then turn the knob or click the button to switch the measured quantity: FREQ F= frequency COUNTR C= count POS-PW H= positive (logical high) period NEG-PW L= negative (logical low) period PERIOD T= time period DUTY DUTY= duty cycle (percent) -

• Next, select the sweep time setting mode, and rotate "ADJUST" knob to adjust the sweep time between 1s and 600s, e.g. to 10s as shown below: • Next, enter the sweep mode selection screen, and choose between LINE (linear frequency sweep) and LOG (logarithmic sweep). •... -
Page 16: Care And Maintenance
Care and maintenance 1. Make sure to use the provided DC5V power adapter; 2. The instrument display LCD module is fragile and needs to be pro- tected from mechanical and chemical damage. Clean by gently wiping with a soft cloth. 3. - Page 17 Warranty conditions: Instrument is warrantied for a period of one year from the shipment date. During the warranty period, the company will repair or replace equipment selected according to the situation. For service, please send the product to the company. The following conditions are not covered under warranty: •...
