1-3 Instrument Care and Preventive Maintenance General Information
1-4 PN: 10580-00480 Rev. A MS27201A UG
1-3 Instrument Care and Preventive Maintenance
Instrument care and preventive maintenance consist of proper operation in a suitable environment, occasional
cleaning of the instrument, and inspecting and cleaning the RF connectors and all accessories before use.
Clean the instrument with a soft, lint-free cloth dampened with water or water and a mild cleaning solution.
Ventilation and Cooling
The Remote Spectrum Monitor provides active cooling of the internal components to prevent damage from
overheating. The airflow vents on the edges and bottom of the instrument must be kept clear and unobstructed
while the instrument is powered on. When using the Remote Spectrum Monitor on a desktop, bench or the
instrument can be placed flat on its back to facilitate increased airflow.
Connector Care
Clean the RF connectors and center pins with a cotton swab dampened with denatured alcohol. Visually
inspect the connectors. The fingers of the N(f) and K(f) connectors and the pins of the N(m) and K(m)
connectors should be unbroken and uniform in appearance. If you are unsure whether the connectors are
undamaged, gauge the connectors to confirm that the dimensions are correct. Visually inspect the test port
cable(s). The test port cable should be uniform in appearance and not stretched, kinked, dented, or broken.
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the Type-N and Type-K
connectors. The recommended torque is 12 lbf·in to 15 lbf·in (1.36 N·m to 1.70 N·m). Inadequate torque
settings can affect measurement accuracy. Over-tightening connectors can damage the cable, the connector,
the instrument, or all of these items.
Visually inspect connectors for general wear, cleanliness, and for damage such as bent pins or connector rings.
Repair or replace damaged connectors immediately. Dirty connectors can limit the accuracy of your
measurements. Damaged connectors can harm the instrument. Connection of cables carrying an electrostatic
potential, excess power, or excess voltage can damage the connector, the instrument, or both.
Connecting Procedure
1. Carefully align the connectors. The male connector center pin must slip concentrically into the contact
fingers of the female connector.
2. To tighten, turn the connector nut, not the connector body. Major damage can occur to the center
conductor and to the outer conductor if the connector body is twisted.
3. If you use a torque wrench, initially tighten by hand so that approximately 1/8 turn or 45 degrees of
rotation remains for the final tightening with the torque wrench.
4. Relieve any side pressure on the connection (such as from long or heavy cables) in order to assure
consistent torque. Use an open-end wrench to keep the connector body from turning while tightening
with the torque wrench. Do not over-torque the connector.
Disconnecting Procedure
1. If a wrench is needed, use an open-end wrench to keep the connector body from turning while loosening
with a second wrench.
2. Complete the disconnection by hand, turning only the connector nut.
3. Pull the connectors straight apart without twisting or bending.
Caution To avoid damaging the case, do not use solvents or abrasive cleaners.
Caution Do not operate or store the Remote Spectrum Monitor in extreme environments. Refer to the
instrument Technical Data Sheet for the specified operating and storage conditions.

ESD Caution
The Remote Spectrum Monitor, like other high performance instruments, is susceptible to electrostatic
discharge (ESD) damage. Coaxial cables and antennas often build up a static charge, which (if allowed to
discharge by connecting directly to the instrument without discharging the static charge) may damage the
Remote Spectrum Monitor input circuitry. Instrument operators must be aware of the potential for ESD
damage and take all necessary precautions.
Operators should exercise practices outlined within industry standards such as JEDEC-625 (EIA-625),
MIL-HDBK-263, and MIL-STD-1686, which pertain to ESD and ESDS devices, equipment, and practices.
Because these apply to the Remote Spectrum Monitor, it is recommended that any static charges that may be
present be dissipated before connecting coaxial cables or antennas to the instrument. This may be as simple as
temporarily attaching a short or load device to the cable or antenna prior to attaching to the Remote Spectrum
Monitor. It is important to remember that the operator may also carry a static charge that can cause damage.
Following the practices outlined in the above standards will ensure a safe environment for both personnel and
equipment.
1-4 Calibration and Verification
The Remote Spectrum Monitor comes fully calibrated from the factory and there are no field-adjustable
components. Anritsu recommends annual calibration and performance verification by local Anritsu service
centers.

8 lbf·in (0.9 N·m or 90 N·cm). The recommended torque for Type N is 12 lbf·in (1.35 N·m or 135 N·cm).
2. Status Indicator
The status indicator illuminates when power is applied to the instrument.
3. Data Out Port
The Data Out port is used for IQ Streaming. Refer to Chapter 6, “IQ Capture/Streaming (Option 124/125 and
126/127)”. This is a multi-purpose, hot pluggable input/output (I/O) interface.
4. USB 3.0 Interface – Type A
The Remote Spectrum Monitor has two Type A USB connectors that accept USB storage devices for saving
measurements, setup data, and screen images. To ensure the device or it’s data does not become corrupted,
click the eject icon to eject (unmount) the USB device before it is unplugged from the USB port (see
Section 2-9 “Title Bar” on page 2-15).

7. Trigger In/Out
A TTL signal that is applied to the external trigger 50 SMA connector causes a single sweep to occur. In
spectrum analysis, triggering is generally used in zero span, and triggering occurs on the rising edge of the
signal. After the sweep is complete, the resultant trace is displayed until the next trigger signal arrives.
8. Trigger In/Out / Ref Out (10 MHz)
This port can be configured as a trigger in/out as above or as a reference output. The reference output port is a
50 SMA female connector that provides 10 MHz at approximately –7 dBm to 0 dBm.
9. Ref In
The external reference input port is a 50 SMA connector that provides for input of an external frequency
reference. Refer to your technical data sheet for valid frequencies. The instrument automatically selects the
frequency reference in the following order of priority: external, GPS, then the internal time base.
10. IF Out
This 50 SMA connector provides internal IF output. The nominal frequency range is 325 MHz with
FFT capture bandwidth ≤32 MHz and 300 MHz with FFT capture bandwidth = 100 MHz. The nominal
RF output level is –4 dBm with a 10 MHz, –20 dBm input, and with 0 dB input attenuation and preamp off.
The spectrum can be inverted in certain RF input bands.

Warning
When using the AC-DC Adapter, always use a three-wire power cable that is connected to a
three-wire power line outlet. If power is supplied without grounding the equipment in this manner, the
user is at risk of receiving a severe or fatal electric shock.

3. Service Port
The service port is for Anritsu customer service use only.
4. Cooling Fan
The cooling fan ventilates the internal heat from the instrument. Keep the fan inlet and exhaust ports clear of
obstructions at all times for proper ventilation and cooling of the instrument.
5. Security Lock
The security lock slot accepts standard laptop cable locks.
2-3 Turning On the MS27201A RSM
The Anritsu MS27201A RSM is operated from a 15 VDC source connected to the rear panel. This can be
achieved with either the Anritsu AC-DC adapter or the automotive power adapter, which can be purchased as
an optional accessory. Refer to the instrument Technical Data Sheet for more options and accessories.
The Remote Spectrum Monitor automatically turns on when power is applied to the rear panel power input
port and takes approximately 60 seconds to completely power-up and to load the instrument software. At the
completion of this process, the instrument is ready for use.
2-4 MS27201A PC Software
The MS27201A PC software provides remote access to a network connected instrument and displays the
MS27201A user interface, instrument controls, and live measurement data on the computer screen. The
software also allows you to load measurement and setup data from saved files and then perform measurement
analysis on the recalled traces, even when instrument hardware is not available or is not connected to the PC
by using the localhost (refer to “Connecting to the MS27201A or Localhost” on page 2-7). The user interface
provides the same functionality when an instrument is connected with the exception that file operations will
interface with the PC file system rather than on the instrument, and save on event operations will be saved to
the instrument memory (refer to “Files” on page 2-30).
Connecting to the localhost is like connecting to an instrument so there is no expectation of carrying over
settings or trace data from one to the other. The localhost will include option controlled functionality with most
options automatically enabled (refer to “GUI Overview” on page 2-8).
Caution
When using the Automotive Power Adapter, always verify that the supply is rated for a minimum of
75 watts @ 15 VDC, and that the socket is clear of any dirt or debris. If the adapter plug becomes hot
to touch during operation, discontinue use immediately.
Note Keep the fan inlet and exhaust ports clear of obstructions at all times for proper ventilation and
cooling of the instrument.
