1.PRODUCT INTRODUCTION

1-1. Description

The GRS-6052A and GRS-6032A 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 sho ts with a full 100MS/s sample rate. The i nstruments provide with a high speed A/D converter for each channel to enable the measurement, memory, and analysis of high-speed phenomena. A microprocessorbased 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 1mV to 20V per division. The horizontal deflection system provides sweep time from 100s to 0.2μs per division. The trigger system provides stable triggering over the full bandwidth of the vertical deflection system.

1-2.Features

Additionally, the oscillo scope off ers seve ral othe r feat ures:

1) High intensity and internal graticule CRT The oscilloscope employs a high intensity 6-inch rectangular type cathoderay 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 z Digitizing repetitive waveform up to full bandwidth 50/30MHz through

the use of equivalent sampling (500MS/s).

z 2k-word acquisition memory per channel up to 10 sets SAVE/RECALL

reference memories (with back-up) are provided.

z Pre-trigger function for observing waveforms before triggering. The

trigger point can be selected from 0~10 DIV (in 0.02DIV steps).

z Roll mode is ideal for observing flickering low-speed signals. The

TIME/DIV range up to 100s.

z The peak detect mode can detect glitch with pulse duration of 25ns or

more.

z The persistence mode makes for easy measurements of jitter, voltage

variation, and etc.

z The averaging function can be selected freely from 2 to 256. This

effectively reduces noi se fr om repe titive sign al s.

z The smoothing (dot-join) function provides linear connections between

the captured point, ensuring that digitized signals are displayed without gaps.

z In the magnification mode, the DOT or LINEAR interpolation can be

selected according to the waveform.

USER MANUAL

z The built-in RS-232C interface enables remote control operation and

signal processing via a PC.

z The X-Y mode is same as the real ti me mode. The X (horizontal ) signal is

connected to the input of CH1, 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 ×5, ×10, ×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 separa tor 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 CH1 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 signa l while ob serving it s wavef orm.

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×130H×370D) mm and front panel layout groups for easyto-use.

USER MANUAL

△V: Two horizontal cursors appear. The voltage between the two cursors is

calculated according to the setting of VOLTS/DIV, and displayed with △V on the upper side of the CRT.

Single channel mode (CH1 or CH2):

The △V measuring result is automatically related to the deflection coefficient of the active channel. The readout displays “△V1…” or “△V2…”.

Dual channel mode:

The cursor lines must be set on the CH1 or CH2 signal. As the deflection coefficients may be different, it will be required to select between the deflection coefficient of CH1 and CH2.

ADD mode:

In ADD (addition) mode, normally two input signals are displayed as one signal (sum or difference). As the result can only be determined if both (calibrated) deflection coefficients are equal, the readout indicates “ △ V…” without any additional channel information. Different deflection coefficient settings or uncalibrated deflection coefficients are indicated in the readout as “△V=…DIV”.

X-Y mode:

In the X-Y mode, the instrument is automatically set to △ V measurement. The deflection coefficient selected for each channel may be different, thus as in DUAL mode the △V cursor measurement requires a channel selection. Under channel 1 (X signal) measuring condition the cursor line s are disp lay ed a s verti cal l ines and the re adout displays “△VX…”. Pressing the pushbutton, select channel 2 (Y signal) measuring, then the cursor lines are displayed as horizontal lines and the readout indicates “△VY…”.

5-2.Connecting Input Signals

Grounding

The most reliable signal measurements are made when the oscilloscope and the unit under test are connected by a common reference (ground lead) in addition to the signal lead or probe. 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 ×1/×10 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 acc uracy of a displayed waveform. To maintain original frequency characteristics of the input signal, use only highquality, low-loss coaxial cables. Coaxial cables must be te rminated at both e nds in their characteristic impedance to prevent signal reflections within the cable. Use suitable impedance-matching devices.

Observing the Synchronization of two Waveforms

When two signals of the CH1 and CH2 have the same frequencies with an integral number, or a specific time difference, the SOURCE selects either CH1 or CH2 as a reference signal. Select CH1 signal from CH1 position and select CH2 signal from CH2 position as a refe rence. Set the SOURCE to VERT-MODE for observing the signal of different frequencies. Switch the sync signal alternately to each channel, the waveform of each channel will be trigge red stab ly. When set the SOURCE to VERT-MODE and set the ALT/CHOP to ALT, the input signals applied to CH1 and CH2 will become trigger source alternately during sweep. Consequently, even the waveforms of different frequency of each channel can be triggered stably. Apply a sine wave to CH1 and a square wave to CH2, “A”s sho wn in Figure 511 are at the level possible for synchronization.

The operation procedure of the digital storage functions is described below.

Normal Sampling mode (SMPL)

1) Display the wa veform to be stored in the REAL TIME mode.

2) Press the STORAGE pushbutton switch and the RUN LED is on.

3) 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.

4) When the TIME/DIV control is from 1μs/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 0.2μs/DIV to 0.5μs/DIV ( 2 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 5 seconds or more to store the inpu t signal of 1kH z or lower. When t he

low frequency signal is stored, noise can be mixed. It is recommended to use a

sine wave of 1MHz or higher or a square wave with the rise time which is

faster than 0.3μs.

Figure 5-17 NOTE: Aliasing:

While measuring the signal in such STORAGE mode as SMPL, AVG, etc., the aliasing can be occurred by inputting a signal of more than half of the frequency with respect to th e sample clock frequency at the sweeping range is added. 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.

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.

SMPL(0.1s~1μs/div)

In normal sampling mode, the instrument generates a record point by saving the first sample during each acquisition interval.

PEAK(100s~5μs/div at one channel, 0.5ms~5μs/div at two channels)

The peak detect mode stores the minimum and maximum values (pairs) for each time bucket. This mode is capable of detecting glitches of 25ns or more regardless of the sweep rate.

PERSIST(0.1s ~0.2μs/div)

The persistence mode displays the minimum and maximum values mutually in the normal sampling and initialization by changing the TIME/DIV control knob. This mode can acquire and display a waveform record that shows the total variation over entire acquisition.

ENVELOP (0.1s ~5μs/div at one channel, 0.5ms~5μs/div at two channels)

The Envelope mode activates both peak detect and persistence mode. This mode monitors signal variations over time. You can measure interference signals, jitter, amplitude modulated signals and more.

AVERAGE (0.1s ~0.2μs/div)

In the Average mode, pressing the VARIABLE control knob to set the number of average, turning the knob clockwise to change the number from 2 to 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). 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.

2) Smoothing selection mode

When the “MENU 1: SMOOTH” is displayed at the top right of the CRT, the smoothing is made on and off.

MENU1 : SMOOTH OFF

OFF: No Smoothing Setting marker by VARIABLE

ON: Smoothing In case of OFF, the storage waveform is displayed by dots, while changing to ON, the dots are connected smoothly as result of a smooth waveform display. 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.

3) Interpolation Method Selection mode

When the “MENU 3: INTRPL” is displayed at the top right of the CRT, THE interpolation Method can be selected.

MENU 3 : I NTRP L DOT

DOT: No interpolation Setting marker by VARIABLE

LINEAR: Linear interpolation The mode selection is made by the VARIABLE control knob. The interpolation method is how to interpolate the magnified data while magnifying the display waveform in the horizontal direction (except for the SAVE/RECALL reference waveform). In the case of DOT, the

5-7.Measurement Application

The oscilloscope has a cursor measurement system for making accurate, directreadout voltage, time and frequency measurements. The measurements described in this section are examples of typical applications using this measurement system. After becoming familiar with the c ontrols, indicators, a nd capabilities of the instrument, you ca n develop convenie nt methods to make the special measurement for your own applications. Proceed a measurement by using the cursor according to the following steps:

1. Press the [△V—△T, 1/△T—OFF] pushbuttons to turn on the cursor and

measurement readout.

2. Press the pushbutton to select the seven measurement function in the

sequence as below: △ V —△T —1/△T—OF F

3. Press the [C1—C2 TRK] pushbutton to select C1 cursor, C2 cursor and

tracking cursor.

4. Rotate the VARIABLE control knob to position selected cursor. Press one of

the VARIABLE control knob to select FINE or COARSE cursor move speed.

5. Read the measurement value on the screen. Typical measurement readouts

and applications are shown in Figure 5-16. The measurement values are automatically controlled by the VOLTS/DIV and TIME/DIV control settings.

Message Terminator and Message Separator

As there is no signal of end message on RS232 bus, therefore use LF (Line Feed, 0× 0A) as message terminator. 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 ASCI I 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 receive s 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 ? (ASCII) Return:

Combining Commands

You can use a semicolon (;) to combine commands and queries. The GRS-60X2A executes coherent commands in the order it receives them. When you coherent queries, the GRS-60X2A 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 1ms/DIV (016), the query commands (must add 1 byte me ssage terminator)

V 3 ? A ; H 1 ?

Instrument will return the message

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 9. 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 li ne voltage posit ion. (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.
