Block diagrams
According to the highest working frequency, the switch module can be divided into three models:
DC-18GHz, DC-26.5GHz and DC-50GHz. Each model contains four independent single-pole double-throwmechanical switches. The USB can be used to control the switching status of each mechanical switch.

Definitions
The data in this manual are technical indicators that include the measurement uncertainty unless otherwise
noted.
Specifications: All products are guaranteed to meet published specifications at room temperature(approximately 25℃), unless otherwise noted.
Typical: Performance deemed typical implies that 80 percent of the measurement results will meet thetypical published performance with a 95th percentile confidence level at room temperature (approximately25℃). Typical performance is not warranted and does not include measurement uncertainty.
Nominal: This value indicates the expected mean or average performance, or an attribute whose
performance is by design, such as the 50 Ohm connector.

About SIGLENTSIGLENT is an international high-tech company, concentrating on R&D,
sales, production and services of electronic test & measurement instruments.

SIGLENT first began developing digital oscilloscopes independently in 2002.
After more than a decade of continuous development, SIGLENT has
extended its product line to include digital oscilloscopes, isolated handheld
oscilloscopes,

generators,

function/arbitrary

spectrumwaveform

analyzers,

vectorgenerators,

network

RF/MWsignalanalyzers,

digitalmultimeters, DC power supplies, electronic loads and other general purpose
test instrumentation. Since its first oscilloscope was launched in 2005,
SIGLENT has become the fastest growing manufacturer of digital
oscilloscopes. We firmly believe that today SIGLENT is the best value inelectronic test & measurement.
