The Instek GSP-8000 series of spectrum analyzers feature three frequency ranges and are suitable for many applications, including education, R&D verification, as well as test requirements of radio frequency products during production and development stages. The series provides 1Hz ~ 1MHz resolution bandwidth (RBW), 10Hz ~ 3MHz video bandwidth (VBW), -104dBc/Hz phase noise, a 20dB preamplifier, and the lowest noise floor of -160dBm/Hz (typical).

The GSP-8000 provides RBW from 1Hz to 1MHz and provides 1-3-5-10 sequence stages, allowing users to observe the signal in more detail.

This function can simultaneously view and display the relationship between power, frequency and time, and can track changes in frequency and power over time.

The GSP-8000 provides five traces of different colors (Trace1 is displayed in yellow, Trace 2 is fuchsia, Trace 3 is azure, Trace 4 is orange, and Trace 5 is green). Users can collocate the required Detector for test and measurement.

The Detector function provides Pos Peak, Neg Peak, Sample, Normal, Voltage Avg, RMS Avg and Quasi-Peak functions. The Quasi-Peak function can only be used after the EMI option is turned on.

In addition to the functions related to Max Peak, the Peak Search function provides a new settable search for Min Peak. Users can set whether to search for Max Peak or Min Peak.

GSP-8000 provides up to 8 Markers for simultaneous display, and Markers can be assigned to different Traces. It also provides three application functions: N-dB, Marker Noise and Frequency Counter.

• N-dB: N-dB: It can measure the bandwidth when the left and right sides of the Marker value decrease by N-dB respectively.
• Marker Noise: Marker Noise: The current Marker frequency reading can be converted into the dBm/Hz absolute power reading at 1Hz RBW.
• Frequency Counter: Users can set the counter to 1kHz, 100Hz, 10Hz and the most accurate resolution of 1Hz

AM/FM signal analysis measurement parameters, such as amplitude modulation depth (Depth) or frequency deviation (Deviation), distortion (THD) and signal-to-noise and distortion ratio (SINAD), and supports demodulated audio source output.
