The GW Instek GDS-1000B Series is a family of general-purpose digital storage oscilloscopes spanning four bandwidth selections — 50 MHz, 70 MHz, 100 MHz, and 200 MHz — available in 2-channel or 4-channel configurations. Each model in the series provides a 1 GSa/s maximum sample rate and 10 Mpts of memory depth per channel independently, paired with a 7-inch WVGA color display and a 50,000 wfms/s waveform update rate. The series positions itself as an entry-level platform that delivers waveform-capture performance and display capabilities historically associated with higher-tier benchtop oscilloscopes.

Applications named in the datasheet center on general benchtop measurement, debugging of fast-changing and modulated signals, embedded serial-bus development using I²C, SPI, UART, CAN, and LIN, frequency-domain analysis via the 1 Mpts FFT mode, and educational use cases such as Lissajous-figure measurement in X-Y mode. The Go/NoGo output, data log function, and digital filter option extend the platform into production yield-rate screening, long-duration monitoring, and noise-rejection scenarios on the bench.

ValueTronics International stocks, inspects, and tests the GDS-1000B Series in our 20,000 square foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Every unit moving through our facility receives hands-on performance verification before it ships, which means our customers receive an instrument with documented condition rather than a sight-unseen drop-ship from a remote distribution center. This is the structural difference between buying from a pass-through broker and buying from a professional test-and-measurement specialist whose business depends on the next instrument working correctly.

## Brand Heritage

GW Instek is the test and measurement brand of Good Will Instrument Co., Ltd., a Taiwanese instrument manufacturer that has operated independently since the company's founding and maintains its own engineering, manufacturing, and global subsidiary network. The brand has not been acquired or rebranded — the GW Instek name applies consistently across current and prior-generation instruments in this product family.

## Compare Other Models in This Series

The GDS-1000B Series is organized around two architectural choices: bandwidth tier and channel count. Bandwidth selections of 50 MHz, 70 MHz, 100 MHz, and 200 MHz are paired with either a 2-channel-plus-external-trigger configuration or a 4-channel configuration, producing the six models in the family. All models share the same 1 GSa/s maximum sample rate, 10 Mpts per-channel memory depth, 7-inch WVGA display, 50,000 wfms/s update rate, and the full menu of trigger modes, serial bus decoding, math and FFT functions, and 36 automatic measurements.

Because the platform features are common across the series, the model-to-model decision reduces to two questions: how fast is the fastest signal the engineer needs to capture (which sets the bandwidth tier and the corresponding rise-time spec), and how many channels are required to view the test setup simultaneously (which determines 2-channel-plus-external-trigger versus full 4-channel).

Each model below is its own dedicated product page with condition-matched pricing. Each pre-owned unit ships with the standard accessory kit, condition documentation appropriate to its grade, and ValueTronics' performance verification against the manufacturer's published specifications for that model.

Bandwidth and rise time scale together across the family. The GDS-1054B (50 MHz, 4-channel) is rated at 7 ns rise time. The GDS-1074B and GDS-1072B (70 MHz, 4-channel and 2-channel) are rated at 5 ns. The GDS-1104B and GDS-1102B (100 MHz, 4-channel and 2-channel) are rated at 3.5 ns.

Channel count differences also affect the X-Y mode and external trigger configuration. The 4-channel models (GDS-1054B, GDS-1074B, GDS-1104B) support X-Y mode using either CH1/CH2 or CH3/CH4 and route the external trigger through one of the four analog inputs. The 2-channel models (GDS-1072B, GDS-1102B, GDS-1202B) provide a dedicated external trigger BNC. The LAN (Ethernet) interface for RJ-45 10/100 Mbps remote control is specified as available on the 4-channel models.
