Product Description
Descrption
The MSA300 series is a first authentic handheld spectrum analyzer providing good characteristics and abundant
functions in spite of compact, lightweight and inexpensive model. MSA300 series is also the best seller product which continues to be loved for many years and is the smallest size and the lowest price in the world.
MSA338E frequency range from 50kHz to 3.3GHz, For EMI test. Suitable for radiated emission measurement and conducted emission measurement. . Since it has functions such as PK detection, QP detection, AV detection and
RBW 9kHz/120kHz (6dB), it enables the radiated emission measurement and the conducted emission measurement for
precompliance. Furthermore, the magnetic field probe CP-2S (option) finds out
the source of disturbance noise.
Measurement mode and Preset
Three measurement modes shown below are available. The troublesome setting for EMI test is unnecessary because the parameters corresponding to the measurement mode are automatically preset.

Detection mode
MSA338E has three detection modes of PK (peak), QP (quasi-peak) and AV (average). As for the datection level, the relational expression of PK≧QP≧ AV is valid as shown in the figure below. Additionally, PK=QP=AV is correct in case of a narrowband signal like CW wave.
The PK detection is achieved by setting the measurement mode to normal measurement, the detection mode to positive peak and the calculation function to MaxHold. By the way, a signal of time width 200ns or more is detected by
positive peak detector because the sampling speed of A/D converter is 5MS/s. When observing a disturbance noise, the PK detection enables the fast sweep because its time constant is much smaller than QP or AV. Therefore, it is convenient to use the PK detection when narrowing the disturbance noise spectrums out of specification down to small number.
The QP detection is usually used in both of the radiated and conducted emission measurements, and the AV detection is usually used in the conducted emission measurement. The measurement time is shortened if they are finally
used only for the measurement of the spectrums narrowed down by the PK detection.
Resolution bandwidth (RBW)
CISPR provides that the radiated and conducted emissions should be measured with RBW filters of 9kHz and 120kHz respectively. The bandwidth is defined as 6dB width. MSA338E also has five RBW filters besides these two filters, whose bandwidths at 3dB are 3kHz, 30kHz, 300kHz, 1MHz and 3MHz.
Horizontal axis data of 1001 points
Although the spectrum is displayed by 251 points on the horizontal axis of the screen of MSA338E, it is captured by 1001 points per sweep in the instrument. All of these 1001 points are transferred to a personal computer and
displayed on the PC screen after processed by PC software MAS230. The image, therefore, becomes clearer.
Compact and lightweight 1.8kg
The dimensions are as small as 162(W)×70(H)×260(D)mm, and the weight is only 1.8kg including the battery.
It is very convenient for outdoor use and on business trip.
150 minutes battery operation
Ni-MH battery MB300 (option) fully charged enables about 150 minutes battery operation at backlight-off.
Accurate 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 -117dBm
The low average noise level of -117dBm @ 1GHz provides a wide dynamic range.
