Safety regulations

Specific requirements for safety categories

Overvoltage Category CAT III 1000V, CAT IV 600V Suitable Distribution System (CAT III) and Low Voltage Grid (CAT IV) Scenarios

Terminal rated value "V Ω" terminal maximum 1000V DC/AC; Terminal A has a maximum of 10A DC/AC (continuous) and 20A (30 second pulse). It is prohibited to input voltage beyond the range to avoid device damage

Operating environment working temperature+10 ℃ -+40 ℃, humidity 20% -80% (no condensation); Storage temperature -40 ℃ -+70 ℃. Exceeding this range may result in decreased testing accuracy or hardware failure

Grounding requirements require grounding through the power line grounding conductor to avoid the risk of electric shock caused by leakage

Operation Guide: Basic Process and Panel Control

1. Power on/off and self check

Startup process

Environmental inspection: Ensure good ventilation (leave 15.2cm space on the left and right sides, 7.6cm space on the top/rear), and unobstructed heat dissipation holes.

Power connection: Select the corresponding power cord according to the region (such as North America 125V, Europe 230V, refer to Table 1-1), and connect the Rear panel power interface.

Starting power supply:

Press the 'PRINCIPAL POWER SWITCH' button on the Rear panel to power on the standby circuit.

Press the "ON/STBY" button on the front panel to start the instrument and perform a self-test (approximately 3 seconds).

Self check result:

No error: Display "Pass" and enter the SETUP menu.

Error: Display "Fail"+error code (such as "Uncal" requiring UTILITY menu calibration). You can press any key to exit and enter the menu, but the waveform output may not be reliable.

Shutdown process

Press the "ON/STBY" button on the front panel to cut off the power supply to the main circuit.

When not in use for a long time, turn off the 'PRINCIPAL POWER SWITCH' on the Rear panel and unplug the power cord.

2. Key components of the front-end panel

Specific functional operation examples for component categories

MEAS key in function selection area: switch measurement function; F. G key: Switch to function generator mode and press F. G key to enter standard waveform settings such as sine/triangle/square wave

Menu Control Area MENU Column: SETUP (Parameter Configuration), MODE (Run Mode), EDIT (Editor), LOAD/SAVE (File Management), UTILITY (System Settings) Press the EDIT key to enter the initial menu for file editing

Universal knobs in the data operation area: adjust values/select files; Numerical keys (0-9/.+-): input parameters; Unit key (ns/MHz, etc.): Enter the "1"+"MHz" key to specify the unit and set the clock frequency to 1 MHz

Trigger control area TRIGGER INPUT: external trigger input (maximum ± 10 V ₚ₋ₚ); MANUAL key: Manually triggered. In Triggered mode, press the MANUAL key to trigger waveform output once

Output control area CH1/CH2 ON/OFF keys: switch channel output; SYNC/MARK output interface: Sync/Mark signal output. Press the CH1 ON/OFF button, and the LED will light up to indicate that the CH1 waveform output is turned on

Core functional module: Editor and menu configuration

1. Four core editors (EDIT menu)

(1) Waveform Editor (. WFM file)

Function: Create/edit waveform data, supports 3 display formats:

Graphic display: Visualize waveforms, support point drawing, smoothing (spline/linear interpolation), arithmetic operations (absolute value/integral/derivative).

Timing display: Display timing according to data bits (DATA 11-DATA 0), supporting the setting of - pattern (such as NRZ/NRZI encoding).

Table display: Display each point data in binary/hexadecimal/real form, supporting direct editing of numerical values.

Key operations: Select the editing area (left and right vertical cursor), perform cutting/copying/pasting, or insert other waveform files.

(2) Equation Editor (. QU file)

Function: Generate waveforms through mathematical equations, support 100 line equations, compile and generate WFM file.

Support functions: trigonometric functions (sin/cos), exponents (exp), logarithms (log/ln), random numbers (rnd), differentials (diff), integrals (integ), etc.

Example equation: range (0,1ms) sin (2 * pi * x) (generates a single period sine wave within 0-1ms).

(3) Sequence Editor (. SEQ file)

Function: Combine multiple waveform/sequence files and set the number of repetitions for each file (1-65535 times).

Operation process: Select a file from the directory → Set the number of repetitions → Generate a sequence, support "Show Overview" preview of combined waveforms.

(4) Automatic Step Editor (. AST file)

Function: Program waveforms and output parameters (clock/amplitude/filter) step by step, switch one step per trigger, supporting 100 steps.
