8、High amplitude resolution: the minimum amplitude resolution can reach 1mV, amplitude range is 0Vpp~20Vpp.
9、Duty-cycle of each channel can be adjusted independently0.1%-99.9%, the adjusting resolution is 0.1%.
10、Pulse pulse width and pulse cycle time is precisely adjustable, adjust the range of 30nS-4000S
11、Scanning features: linear sweep and logarithmic sweep functions; 0.1s-999.9s sweep time; sorward, backward and roundtrip sweep directions.
12、With pulse trains burst output function, allow the unit output 1~1048575 arbitrary pulse trains.
13、Measurement functions: can measure signal frequency, cycle, positive/negative pulse width and duty cycle; 1Hz~100MHz frequency range.
14、-9.99V~9.99V DC offset range, offset resolution: 0.01V.
15、With digital signal output function, CMOS output range 0~10V.
16、Storage feature: can store 100 groups of parameters set by the user and extract at any time.
17、Counter function: with DC and AC coupling modes.
18、Arbitrary wave editing function: user can edit arbitrary wave on PC and then download to
output from the instrument.
19、Communication function: the PC can be used to control the instrument.
20、With output short-circuit protection: all signal output can work 60s under load short-circuit condition.
