The spectrum analyzer is a member of the oscilloscope family. An electrical signal is fed, by means of a BNC cable or probe, into an input port on the front panel, and its graphic image appears on the LCD screen. But rather than the oscilloscope’s familiar time domain graph, in which amplitude in volts is […]

New budget-minded 200-MHz digital scopes sport 2GS/sec max sample rate
The new TBS2000B Series of Digital Storage Oscilloscopes was developed to meet the performance, usability and affordability needs of both engineers and educators. The TBS2000B scopes extend the performance of the TBS2000 portfolio to 200 MMz with 2GS/sec maximum sample rate. The TBS2000B introduction comes shortly after the release of Tektronix’s Series 3 and 4 […]
High-speed current pulser incorporates dc source and measurement functions
The new 2601B-PULSE System SourceMeter 10-µsec Pulser/SMU integrates a high-speed current pulser with dc source and measurement functions in one instrument. The new system incorporates PulseMeter technology for sourcing current pulses as short as 10 µsec at 10 A and 10 V without the need to manually tune the output to match device impedance up […]
Overview of electrical measuring instruments -Part two
In a recent column, we gave a quick review of some basic instrumentation common to most engineering work benches. Here are a few more instruments found in many engineering labs. Curve Tracer The curve tracer is a member of the oscilloscope family of measuring instruments. In its CRT or flat screen display, the user sees […]
Wideband RF signal analyzer gets combined with streaming recorder
The RSA7100B wideband RF signal analyzer and streaming recorder targets engineers working on the latest wideband designs in communications, radar, and electronic warfare. The solution offers more than 2.5 hours of streaming RF storage at 800-MHz real-time bandwidth and its 16 kHz to 26.5 GHz frequency range covers a broad range of analysis needs. In […]
Do you really need a VNA when a scalar network analyzer might do?
Network analyzers measure network parameters of electrical networks, such as two-port amplifiers and filters. The instruments characteristically operate at 5 Hz to 1.05 THz, mostly at the higher end, though some models are sensitive down to 1 Hz. These instruments are available in two varieties: scalar network analyzers, which measure only the amplitude of the […]
Signal acquisition in the Tektronix MDO3000 series oscilloscope
Most modern digital storage oscilloscopes have either two or four analog channels. One or two channels suffice for most work, but it is just good to know you have four, notwithstanding the substantial cost differential. As for the digital channel count, it is typically 16, handy when working on a parallel bus. All these digital […]
Understanding noise in electronic instrumentation
In measuring or displaying weak signals, noise places the ultimate limit on detectability. It usually appears as a fluctuating horizontal line known as the noise floor in a spectrum analyzer of oscilloscope in FFT or RF mode. In the time domain, it appears as a thickening of the trace and in severe instances, causes a […]
Setting input parameters in the Tektronix MDO3000 oscilloscope
Input parameters in the Tektronix MDO3000 Series Oscilloscope are determined by the user. This is done by pressing one or more of the channel menu buttons, causing the horizontal channel menu to appear. Menu items are: • Scale – Fine, Offset, Position, Probe setup and Deskew • Coupling – ac or dc • Termination – […]
