2680 Series

Technical data subject to change © B&K Precision Corp. 2019 www.bkprecision.com The 2680 Series of spectrum analyzers delivers performance and functionality in a lightweight, compact design, suitable for lab and field use. The large 10.1” wide-screen color display allows the user to visualize the waveform and make precision measurements such as third order intercept, occupied bandwidth, 2D and 3D spectrum monitor. The 2680 Series provides a standard pre-amplifier and tracking generator in both the 2.1 and 3.1 GHz models. The series also includes

1 Hz minimum RBW and advanced measurements,

which make these analyzers perfect for applications in 2 way radio, site surveying, EMI pre-compliance, characterizing the frequency response of RF devices and more.

www.bkprecision.com Operation highlights Low displayed average noise level (DANL) Phase noise -98 dBc/Hz@ 1 GHz, offset 10 kHz. Four independent traces and markers Capture snapshots, continuously update the maximum or minimum value, and perform math on all 4 individually colored traces. Delta markers Powerful delta markers can be used to select amplitude, span, stop, start or center frequency, measure noise level, amplitude or frequency. Take advantage of the preamp and -161 dBm DANL to measure low level signals accurately. Low phase noise for accurate measurements The 2D and 3D spectrum monitor features are standard on the 2.1 GHz and 3.2 GHz models. The 3D spectrum monitor can be displayed using the provided PC software, while the 2D is viewable on the spectrum analyzer screen and in the PC software. This feature shows how the frequency content of a signal changes over time by representing the power intensity with a color gradient. In today’s crowded spectrum, ACPR measurements are critical to ensure compliance with regulations. The 2680 series displays the main channel power, left and right channel power as well as bandwidth for each channel on screen for ease of determining the total power being transmitted and the spectrum being used.

www.bkprecision.com Options PC software Use 3D spectrum monitoring with the PC software.Generate test reports Expand control of the spectrum analyzer with front panel emulation. Create, load or save user defined limit and correction files, save screen captures and store readings from the included software. Reflection bridge Quasi-peak detection with dwell time helps identify non-compliant emissions. Use the provided EMI software (available for download at www.bkprecision.com) to configure the spectrum analyzer, perform prescan, peak search, final scan and generate reports of your pre-compliance tests. Visualize return loss, reflection coefficient, and VSWR of your DUT. This option enables VSWR, reflection coefficient, and return loss measurements for tuning and determining the efficiency of antennas, filters, or RF transmission modules. Reflection measurement option This option enables the instrument’s EMI measurement function which includes pre-defined bandwidth set points of 200 Hz, 9 kHz and 120 kHz, a -6dB EMI filter, and the quasi-peak detector as specified by CISPR 16-1. EMI pre-compliance option The RF energy radiating from a device can be detected and measured with near field probes and the spectrum analyzer. The wide band amplifier can be connected between the probe and the

2680 Series to increase the dynamic range of the

measurement system. The probes can also be used to test RF immunity by inducing signal into the circuit. Near field probe kit Use near field probes to help track down emissions.
