MSA438TG 3.3GHZ Handheld Color Spectrum Analyzer with TG

Product Description

Description:
Frequency range from 50kHz to 3.3GHz, With 5MHz to 3.3GHz tracking generator. The tracking generator is a signal source which generates the sine wave synchronized with the sweep of the spectrum analyzer. For example, the tracking generator outputs 1MHz sine wave when the spectrum analyzer is at 1MHz sweep point. The 1GHz is output at 1GHz sweep point as well. Therefore, the amplitude frequency characteristics of various electronic components and circuits can be observed on the screen without any troublesome operation. Moreover, the VSWR bridge MVS300 (option) enables to measure the return loss.

Frequency response of filter
The input and the output of a filter are connected to TG OUT and RF IN respectively. The frequency response of a filter is observed in the range of 5MHz to 3.3GHz. The frequency response of the coaxial cable and MSA438TG is made flat by using the NORMALIZING function.

Gain characteristics of amplifier
The frequency response of an active circuit such as an amplifier besides a passive circuit such as LC filter is measured. A measurement example of the gain-frequency characteristics of an amplifier is shown in the figure below.
The level of TG OUT is -10dBm.

Return loss measurement
VSWR bridge MVS300 (option) connected to TG OUT and RF IN of MSA438TG enables the return loss measurement. The measured frequency range is from 5MHz to 3GHz. Additionally, the calibration of the return loss 0dB is done by using the NORMALIZING function.

Comparison:
The best-seller model MSA300 series was extremely upgraded to MSA400 series as shown in “Comparison between MSA300 and MSA400 series” table. However, the weight and dimensions are almost same, and the price was suppressed as low as possible.

MSA438 frequency range from 50kHz to 3.3GHz, The most popular model. Suitable for cellular phone, 2.4GHz wireless LAN, 2.5GHz WiMAX, RF-ID and Broadcasting.

USB memory
USB memory can be used as a removable storage. The screen image is stored by BMP format,
and the spectrum and the setting parameters are stored by CSV format.

USB communication
Such fast transfer rate as 12Mbps maximum was achieved by adoption of USB interface.

Accrate frequency measurement by PLL synthesizer
The center frequency is accurately set by PLL (Phase Locked Loop) synthesizer.
Moreover, the frequency counter (factory option) enables to measure the frequency of the signal more accurately.

Average noise level　-127dBm
The low average noise level of -127dBm @1GHz provides a wide dynamic range.

100dB display dynamic range
As the display scale in the amplitude axis is 100dB/10div, the signal is observed in a wide dynamic range.

Easy operation by AUTO mode

• Auto range operation: RBW, VBW and sweep time are automatically selected based on the frequency span.
• Auto tuning operation: The center frequency is adjusted to the maximum level within full span, and the optimum RBW, VBW and sweep time are chosen.

Competitive functions

• Measuring functions: Channel power, Adjacent channel power, Occupied bandwidth, Electric field strength, Magnetic field strength and Frequency measurement.
• Calculation functions: Max hold, Min hold, Averaging, Over write
• Marker measurement and peak search function
• Save/Load function
• Hard copy with printer

Abundant options
A lot of options such as PC software, Logging software, VSWR bridge, Dipole antenna, Magnetic field probe,
USB printer, Frequency counter, Lithium-ion battery and Test accessories are available.
