Equipment information:

Anritsu MS610J1 Spectrum analyzer
Manufacturer:
Anritsu
Model: MS610J1
Date: 1986
Category: Measurement instruments
Group: Spectrum analyzer
Description:
Information:
                                    The MS61 OB/J Spectrum Analyzer has a wide frequency
range of 10 kHz to 2 GHz, and covers a broad range
from the video to the UHF/VHF bands.
The MS610B/J also has a high harmonic dynamic range
of 80 dB or more, so the time required for higher
harmonic and spurious measurements is significantly
reduced.
The coupled functions are provided to simplify operation.
In the coupled mode, the only required operation is
to set frequency, frequency span, and reference level.
The GP-IB and QP (Quasi Peak) detector for radio interference
(EMI) measurement (options) are available for wider
applications.
Frequency and frequency response can be accurately
measured by using the MH680B Tracking Generator and
a counter with the MS610B/J.
The MS610B/J is easy to transport, features compact
design, is lightweight, and has low power consumption.
It can also be operated on battery-power in the field.
The input impedances are 50Ω for the MS610B, and 75Ω
for the MS610J.
