Core Function Operation Guide
(1) Vertical and horizontal control
Analog signal channel configuration (CH menu)
Basic settings: Can control waveform display switch, input coupling (AC/DC/DC50), probe parameters (attenuation ratio, etc.), waveform inversion, linear scaling, label display, bandwidth limitation, offset, etc. When the input coupling is AC, low-frequency signals or low-frequency components may be attenuated, and attention should be paid to the integrity of signal monitoring; The DC50 mode displays the DC and AC components of the signal through 50 Ω.
Safety restrictions: The maximum voltage for a 1M Ω input is 300 Vrms or 400 Vpeak (100kHz and below), and for a 50 Ω input, the maximum voltage is 5 Vrms or 10 Vpeak. Overvoltage may damage the input part; When changing the input coupling, attention should be paid to the actual coupling state changes during the next waveform acquisition.
Offset cancellation: The offset cancellation function can be turned on/off through the system configuration in the UTILITY menu, and the offset setting is applicable to all input coupling modes. When the probe attenuation changes, the vertical scale will be scaled according to the new attenuation ratio. When the offset value exceeds the range, it will be automatically adjusted to the maximum value. After restoring the original vertical scale, the offset value will be restored.
Channel information copying (CH UTIL menu): The analog signal input settings of one channel can be copied to other channels by selecting the source channel and target channel. The channel ranges that can be copied for 8-channel and 4-channel models are CH1-CH8 and CH1-CH4, respectively. When copying, the source channel is light gray and cannot be selected separately. When selecting all channels collectively, although the source channel is checked, copying will not be performed.
Logic signal setting (LOGIC menu)
Basic functions: Control logic signal waveform display switch, bit setting (display switch, label, threshold level, noise suppression, etc.), bus display (switch, bit allocation, label, format, etc.), bit and bus display sequence, status display (switch, clock source, polarity, etc.), offset correction.
Collection restriction: When the record length in the ACQUIRE menu is set to the maximum value, the waveforms of LOGIC ports C (C0-C7) and D (D0-D7) cannot be collected.
Threshold and noise: The 701989 logic probe can set the threshold type (All/Each), and selecting the preset threshold will automatically configure it. After changing it, the preset will become "Userdef"; The noise suppression function is only available for probe 701989, and the level and noise suppression in the bit setting will be synchronized to the setting when the trigger source is Logic.
Vertical axis setting (SCALE/POSITION knob)
Analog signal: Press the CH1-CH8 keys to select the channel, adjust the vertical scale with the SCALE knob, and press the knob to enter FINE mode for high-precision adjustment; Adjust the vertical position with the POSITION knob, press it to set the position to 0 div. When adjusting, the corresponding channel information display area will temporarily display the relevant values, and there will be an out of range prompt.
Logic signal: Press the LOGIC key to control the display size of the logic signal on the SCALE knob, adjust the vertical position on the POSITION knob, and the LED will display the symbol color of the corresponding channel or logic signal.
All on/off (CH UTIL menu): It can collectively display or hide all analog signal channel waveforms, and logic signals do not have this collective control function.
Horizontal scale setting (TIME/DIV knob): Adjust the sensitivity of the horizontal scale, and temporarily display the time scale value and recording length in the upper right corner of the screen when controlling; ◄ POSITION ► Rotate the knob to adjust the horizontal position of the waveform, synchronously move the trigger position, press to set the trigger position to 50%, and adjust the waveform display in real-time during collection and operation.
(2) Trigger function
Trigger mode and hold time (MODE menu)
Trigger modes: including Auto (automatically updates waveform when triggering conditions are met or timeout occurs, with timeout of 100ms or the larger value of 10 time axis scales, and enables scrolling mode when the time axis exceeds the threshold), Auto Level (automatically sets the trigger level to the center value of the trigger source amplitude and triggers when timeout is not triggered), Normal (updates only when triggering conditions are met), N Single (stops and displays after collecting a specified number of signals), Single (presses the SINGLE button on the panel, collects waveform once and stops after triggering).
Holding time: Set through the Holdoff soft key to prevent accidental triggering, adjustable through jog shuttle or on-screen numeric keypad.
Collection Count: In N Count mode, the number of collected waveforms can be set, which can also be configured through jog shuttle or on-screen numeric keypad.
Trigger position and delay (◄ POSITION ►/DELAY key)
Trigger position: ◄ POSITION ► knob adjustment, temporary display of position value at the top of the screen during control, can also be set when no waveform is collected.
Trigger delay: After pressing the DELAY key to enable it, adjust the delay value with the ◄ POSITION ► knob, and the screen will temporarily display at the top. Press the DELAY key again to switch back to the trigger position setting; The delay cancellation function is enabled/disabled through the UTILITY menu system configuration. When enabled, the time measurement is based on the trigger position of 0s (no delay applied), and when disabled, the trigger point is 0s (delay applied), and the delay value is not affected by changes in the horizontal scale.
Various trigger settings (EDGE/ENHANCED/B TRIG menu)
Edge trigger (EDGE menu): Select the trigger source (CH1-CH8/Logic/EXT/LINE), set the trigger slope, high-frequency suppression, noise suppression, and trigger level. The settings for different sources (such as Logic requiring source position, EXT requiring probe attenuation and input range) may vary; LINE source only triggers rising edge.
Enhanced Trigger (ENHANCED Menu): Includes multiple types, such as multi edge trigger OR (select trigger source channel and slope, set trigger level for each channel, high-frequency/noise suppression), multi input mode trigger (set clock source, trigger source mode and combination conditions, time conditions, etc.), pulse width trigger (select source, polarity, high-frequency/noise suppression, trigger level, set time conditions and reference time, trigger when pulse width and reference time relationship are met), as well as rise/fall time trigger, runt signal trigger, timeout trigger, window trigger, etc. Some trigger types (such as bus signal trigger) are optional functions.
Combination trigger (B TRIG menu): Set the combination method of trigger A and trigger B (OFF/A Delay B/A to B (N)). In A Delay B mode, trigger A after it satisfies the specified time delay, and trigger B when it satisfies the specified time delay; In the A to B (N) mode, when A is triggered and B is triggered N times, it can be triggered, and both A and B can choose multiple types of edge triggering or enhanced triggering (such as bus signal triggering). However, when B is triggered through a window, the time limit is fixed at None, and the triggering condition for the mode without a clock source cannot be selected as True/False.
