Ceyear, the new brand name of the China Electronics Technology Instruments Co. Ltd. (CETI), makes powerful measurement solutions at attractive prices, enabling businesses with tight equipment budgets to afford more measurement capability.
The AV4051 signal and spectrum analyzer is one example, offering excellent dynamic range, phase noise and test speed and available with nine upper frequency options, from 4 to 67 GHz. Coverage to 500 GHz is possible with an external mixer. The displayed average noise level (DANL) of the analyzer is ‐156 dBm/Hz at 1 GHz, ‐141 dBm/Hz at 50 GHz and ‐135 dBm/Hz at 67 GHz. The AV4051 has three analysis bandwidth options: 10, 40 and 200 MHz, adjustable to more than 40 levels from 10 Hz to the maximum bandwidth. With 4 GB of memory, data streams can be recorded from 2 s to several hours, depending on the selected bandwidth.
The instrument’s spectrum analysis capabilities include sweep and FFT sweep, zero span fast sweep (1 µs), frequency counting with 0.001 Hz resolution and test functions for occupied bandwidth, channel power, adjacent channel power, harmonic distortion and third-order intercept. The AV4051 performs transient analysis, with time-domain and frequency-domain correlation, and provides a waterfall display showing spectrum changes versus time. Phase noise testing is also part of the analyzer’s capabilities.
The unit has a 10.1-inch LCD display with 1280 × 800 pixel resolution and supports USB, LAN and GPIB interfaces. Outputs include digital, 1× or 4× optical fiber and a real-time interface for recording I/Q data. An external digital recorder supports SSD and HDD media.
AV4051 pricing starts at $25,500, which is very competitive with other signal and spectrum analyzers.
