GBS-1000 Series User Manual Do not dispose electronic equipment as unsorted municipal waste. Please use a separate collection facility or contact the supplier from which this instrument was purchased. Safety Guidelines General Guideline CAUTION  Make sure the BNC input voltage does not exceed 300V peak.  Never connect a hazardous live voltage to the ground side of the BNC connectors. It might lead to fire and electric shock.  Do not place any heavy object on GBS-1000.
PAGE 7
SAFETY INSTRUCTIONS Power Supply WARNING Fuse WARNING Cleaning GBS1000 Operation Environment  AC Input voltage: 100 ~ 240V AC, 48 ~ 63Hz  The power supply voltage should not fluctuate more than 10%.  Connect the protective grounding conductor of the AC power cord to an earth ground, to avoid electrical shock.  Fuse type: T2A/250V  Make sure the correct type of fuse is installed before power up.  To ensure fire protection, replace the fuse only with the specified type and rating.

GBS-1000 Series User Manual (Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements as follows. GBS-1000 falls under degree 2. Pollution refers to “addition of foreign matter, solid, liquid, or gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”.  Pollution degree 1: No pollution or only dry, non-conductive pollution occurs. The pollution has no influence.  Pollution degree 2: Normally only non-conductive pollution occurs.

MEASUREMENT Basic Measurement This section describes the basic operations required in capturing and viewing the input signal. For detailed operation, see the following chapters.  Measurements → from page51  Configurations → from page92 Channel activation Activate channel To activate an input channel, press the Channel key. The LED turns On and the input signal waveform appears on the display. De-activate channel To disable the channel, press the Channel key again.
PAGE 54
GBS-1000 Series User Manual Auto Set Background Panel operation Auto Set function automatically configures the panel settings to position the input signal for the best viewing conditions. The GBS-1000 automatically configures the following parameters.  Horizontal scale  Vertical scale  Trigger source channel 1. Connect the input signal to GBS-1000 and press the Auto Set key. Auto Set 2. The waveform appears in the center of the display. Before After 3. To undo Auto Set, press F5 (Undo).
PAGE 55
MEASUREMENT Run/Stop Background By default, the waveform on the display is constantly updated (Run mode). Freezing the waveform by stopping signal acquisition (Stop mode) allows flexible observation and analysis. To enter the Stop mode, two methods are available: pressing the Run/Stop key or using the Single Trigger mode. Stop mode icon When in Stop mode, the Stop icon appears at the top of the display. Freeze waveform 1. Press the Run/Stop key by Run/Stop key once.

GBS-1000 Series User Manual Horizontal position/scale For detailed configuration, see page108. Set horizontal position The horizontal position knob moves the waveform left/right. As the waveform moves, the memory bar appears on the top of the display, indicating the portion of the displayed waveform that is in memory. Stop mode In the Stop mode, the memory bar moves along with the waveform until it reaches the end of the memory.
PAGE 57
MEASUREMENT Vertical position/scale For more detailed configuration, see page118. Set vertical position To move the waveform up or down, turn the vertical position knob for each channel. As the waveform moves, the vertical position of the cursor appears at the bottom left corner of the display. Run/Stop mode Select vertical scale The waveform can be moved vertically in both Run and Stop mode. To change the vertical scale, turn the VOLTS/DIV knob; left (down) or right (up).

GBS-1000 Series User Manual Probe compensation signal Background This section introduces how to use the probe compensation signal for general usage, in case the DUT signal is not available. For probe compensation details, see page172. Note that the frequency accuracy and duty factor are not guaranteed. Therefore the signal should not be used for reference purpose. Square waveform for probe compensation. 1k ~ 100kHz, 5% ~ 95%. Waveform type Demonstration signal to show the effect of peak detection.

Hardcopy Once set, each subsequent save only requires pressing the Hardcopy key. The Hardcopy key can be configured into three operations: save image, save all (image, waveform, setup), and printing. The printing operation is described in page163. Using the Save/Recall key can also save files but with greater configuration options. For details, see page145.
