Description The GRS-6052 and GRS-6032 set a standard in performance and economy, each equips with two professional scopes in one. They can be operated as a real time 50 or 30MHz analog oscilloscope and become a full function digital storage oscilloscope by pressing a button. Now, you have the power for digital capture and analysis of elusive single shots with a full 20MS/s sample rate. The Instruments provide with a high speed A/D converter for each channel to enable the measurement, memory, and analysis of high-speed phenomena. A microprocessor-based operating system controls most of the functions of the instrument, including cursor readout and digitized panel setting. On-screen alphanumeric readout and cursor function for voltage, time and frequency measurement provide extraordinary operational convenience. Ten different user defined instrument settings can be saved and recalled without restriction. The vertical deflection system has two input channels. Each channel has 14 basic deflection factors from ImV to 20V per DIVision. The horizontal deflection system provides sweep time from 100s to 0.2 u per DIVision. The trigger system provides stable triggering over the full bandwidth of the vertical deflection system. GRS-6052/6032 OSCILLOSCOPE USER MANUAL os ЛЕНЕ DC НН 1-2.Features Additionally, the oscilloscope offers several other features: 1) High intensity and internal graticule CRT The oscilloscope employs a high intensity 6-inch retangular type cathode-ray tube with red internal graticule. It displays clear readable traces even at high sweep speeds. Internal graticule lines eliminate parallax-viewing error between the trace and the graticule line. 2) Multiple Digital Storage Functions Digitizing repetitive waveform up to full bandwidth 50/30MHz through the use of equivalent sampling (500MS/s). 2k-word acquisition memory per channel up to 10 sets SAVE/RECALL reference memories (with back-up) are provided. Pre-trigger function for observing waveforms before triggering. The trigger point can be selected from 0-10 DIV (in 0.02DIV steps). Roll mode is ideal for observing flickering low-speed signals. The TIME/DIV range up to 100s. The averaging function can be selected freely from 2 to 256. This effectively reduces noise from repetitive signals. The smoothing (dot-join) function provides linear connections between the captured point, ensuring that digitized signals are displayed without gaps. In the magnification mode, the DOT or LINEAR interpolation can be selected according to the waveform. The built-in RS-232C interface enables remote control operation and signal processing via a PC. GRS-6052/6032 OSCILLOSCOPE USER MANUAL ET ® The X-Y mode is same as the real time mode. The X (horizontal) signal is connected to the input of CHI, the Y (vertical) signal is applied to the input of CH2, and the storage waveform bandwidth up to 50MHz/30MHz. 3) ALT-MAG Function (both Real Time Mode and Storage Mode) The primary sweep waveform along with the magnified sweep waveform can be displayed simultaneously using the ALT-MAG function. The magnification ratio can be selected from among three stages of Хх 5. Хх 10, xX 20 for magnifying the displayed waveform in the center of the CRT. 4) Convenient VERT-MODE Triggering The sync signal source is decided automatically when vertical axis mode is switched. This means that you need not change the trigger source every time you switch the VERT-MODE. 5) TV triggering Exclusive TV sync separator circuit technology provides stable TV signal measurements on fields, frames and lines. 6) Hold Off (Real Time Mode only) The function allows the obtaining of stable synchronization for even complex waveforms that are difficult to synchronized by adjusting the trigger level alone. 7) CH1 Signal Output The CHI signal output is obtained by branching the input signal in the middle of the signal line. As the connector outputs the input signal at a rate of 50mV/DIV, connecting a frequency counter makes it possible to measure the frequency of a very low signal while observing its waveform. GRS-6052/6032 OSCILLOSCOPE USER MANUAL |g ОНА, [eee {Pen 8) Z-axis intensity modulation (Real Time Mode only) For applying a blanking signal from an external source. The trace displayed on the screen may be intensity-modulated where pulse signal or time-scale marks are required. 9) LED indicator and buzzer alarm The LED's located in the front panel assist operation and indicated additional information. Incorrect operation and the electrical end position of control knobs are indicated by a warning beep. 10) SMD manufacturing technology The instrument is built by using the most advanced SMD technology so as to reduce the number of internal wiring and shorten the foil route on the pc board. This will also greatly increase the high frequency performance and the reliability of the product. 11) Compact size (275W x 130H x 370D) mm and front panel layout groups for easy-to-use.

The ground lead of the probe provides the best grounding method for signal interconnection and ensures the maximum amount of signal-lead shielding in the probe cable. A separate ground lead (with a banana plug) can also be connected from the unit under test to the oscilloscope ground jack on the front panel. Probes A probe provides the most convenient way to connect an input signal to the oscilloscope. The standard x1/x10 probes supplied to the oscilloscope are shielded against electromagnetic interference and have a high input impedance for low circuit loading. CAUTION. To get the best waveform precisely, keep probe ground and signal leads as short as possible. Misadjust probe compensation can cause measurement error. Check and adjust probe compensation whenever a probe is moved to a different channel or oscilloscope. As for the probe compensation adjustment procedure, refer to the “Probe Compensation”. Coaxial Cables Signal input cable can greatly affect the accuracy of a displayed waveform. To maintain original frequency characteristics of the input signal, use only high-quality, low-loss coaxial cables. Coaxial cables must be terminated at both ends in their characteristic impedance to prevent signal reflections within the cable. Use suitable impedance-matching devices.

Digital Storage Functions The operation procedure of the digital storage functions is described below. Normal Sampling mode (SMPL) | 1) 2) 3) Display the waveform to be stored in the REAL TIME mode. Press the STORAGE pushbutton switch and the RUN LED is on. In this mode, a waveform is swept every trigger according to the setting state of controls on the front panel, the waveform to be stored is displayed on the CRT as it is. The slower the sweep rate, the longer the time is required for the acquisition and display of the waveform. It takes approximately 3 seconds until a waveform is acquired at the sweep range of 0.1s/DIV. The trigger signal is generated thereafter. Therefore, when the sweep rate is slow, the waveform is not displayed on the CRT immediately after the controls on the front panel have been adjusted. When the TIME/DIV control is from 5 u s/DIV to 0.1s/DIV, both the single and the repetitive waveforms can be stored. Equivalent Sampling Mode (EQU) When the TIME/DIV control knob is set to 0.2 u s/DIV to 24 s/DIV (4 steps), only the repetitive waveform can be stored in the equivalent sampling mode. The first (left end) rising and falling edges of the traces may not be displayed in the repeat mode range. In this case, measure the rising or falling edge on the second or later cycles of the waveform. It takes 3 seconds or more to store the input signal of 1kHz or lower. When the low frequency signal is stored, noise can be mixed. It is recommended to use a sine wave of IMHz or higher or a square wave with the rise time which is faster than 0.3 ss.

Figure 5-16 ROLL mode The displayed waveform is rolled from right to left (0.2s/DIV to 100s/DIV). The right end of each trace is the updating point of a new data. The Roll mode facilitates the measurement of a signal of approximately 100Hz or lower. Press the STOP switch to stop the ROLL mode and hold the final waveform on the CRT.

When the aliasing is occurred, the waveform of the input signal frequency minus the sample clock frequency will be displayed. It is possible that this display is judged a current waveform. If the aliasing is suspected, select the REAL TIME mode and check if the display is the same as that in the actual operation mode. GRS-6052/6032 OSCILLOSCOPE USER MANUAL PRE-TRIGGER Measure the waveform before the trigger point. Although a conventional oscilloscope displays the trigger point only at the left end of the screen since the sweep starts at the trigger point of the signal, the instrument can display the trigger point anywhere on the screen in 0.1DIV steps, using the PRE-TRIGGER function in the STORAGE mode, so that it is possible to measure the waveform before the trigger point precisely. 1) When the MENU and CURSOR functions are off, the position of the trigger point is displayed. 2) The position of the trigger point is set by the VARIABLE control knob. 3) For example, in the case of 4.0DIV setting, the signal before the rising edge of the waveform (the triggered point) can be observed as shown in Figure 5-18 below.

When the sampling frequency is low with respect to the input signal frequency (when the signal of more than 5 cycles per division is connected), the amplitude to be display may be small. In this case, set the smoothing mode to OFF to display the waveform of the similar amplitude with the input signal. The setting can be done by the VARIABLE control knob. GRS-6052/6032 OSCILLOSCOPE USER MANUAL 2) Average setting mode When the “MENU 2: AVERAGE” is displayed at the top right of the CRT, the number of average can be set. OFF : Average is not performed. Setting marker by VARIABLE ~256: Average is performed 2 ~ 256 times. The number of average is selected by the VARIABLE control knob. Turning the knob clockwise to change he number from OFF to 2-4-8-16-32-64-128-256 and turning the knob counter-clockwise to change the number in the reverse order. The average waveform is displayed after the data of the set sweep number has been acquired. When the number of average is 16, the data is acquired 16 times (the RUN LED blinks 16 times). Then the data is averaged and the average waveform display is updated. Thus, the non-repetitive signal affected by asynchronous noise can be picked up. The average operation is performed by setting the number of average. In the ROLL mode, the average operation is not performed.

When a series of commands are sent to the instrument, it must add a LF to be a judgment for message terminator. As for query command, the return message of the instrument is also added a LF for PC to judge message terminator. A semicolon separates one command from another when the commands appear on the same line. Return Data Format If instrument received question mark (?) at the third byte (command type) of the command, it will answers 3 bytes value in ASCII format and 1 byte message terminator of LF (0x0A). The following example ask the Time base scale, and instrument will return 010 (.1s/DIV): Example: H 1 ? (ASCII) Return: 0 1 0 (3 bytes, ASCII format) If instrument receives WA?-WD?. It will return 1000 bytes channel 1, channel 2 or 2 recalled waveforms data in Binary format and 1 byte message terminator, Example: W A ?

Combining Commands You can use a semicolon (;) to combine commands and queries. The GRS-60X2 executes coherent commands in the order it receives them. When you coherent queries, the GRS-60X2 combine the responses into a single response message. For example, if the channel 1 display is ON (001) and horizontal time base scale equals to Ims/DIV (016), the query commands (must add 1 byte message terminator) VI2A;yHI1? Instrument will return the message 001016 . GRS-6052/6032 OSCILLOSCOPE USER MANUAL „EA, Buffer Size The command receive buffer of instrument is 128 bytes. The return message buffer of instrument is 1024 bytes. If your combining commands size is larger than 128 bytes, commands will be lost. If you query the waveform data (WA? or WB?), the instrument will return 1000 bytes waveform data. Do not use any query commands during the data transmission.

Replace fuse /N only with 250V fuse of the specified type and rating, and disconnect power cord before replacing fuse. 6-2.Line Voltage Conversion The primary winding of the power transformer is tapped to permit operation from 100, 120, or 230VAC 50/60Hz line voltage. Conversion from one line voltage to another is done by changing the line voltage selector switch as shown in page 7. The rear panel identifies the line voltage to which the unit was factory set. To convert to a different line voltage, perform the following procedure: (1).Make sure the power cord is unplugged. (2).Adjust the line voltage selector switch to the desired line voltage position. (3).A change in line voltage may also require a corresponding change of fuse value. Install the correct fuse value as listed on rear panel. — 93 — GRS-6052/6032 OSCILLOSCOPE USER MANUAL 6-3.Cleaning | To clean the oscilloscope, use a soft cloth dampened in a solution of mild detergent and water.
