1.Introduction
The MPM-210H is a multi-port optical power meter for measuring optical
characteristic of optical devices. The MPM-210H is composed of up to five MPM-
211/MPM-212/MPM213/MPM-215 Measurement Modules (MM). There are four
types of measurement modules: MPM-211, MPM-212, MPM-213 and MPM-215.
The MPM-211 MM has 4 optical power measuring ports (4 channels). The MPM-
212 has 2 optical power measuring ports and 2 analog output ports and outputs
analog voltage signal proportional the optical power per each port. The MPM-
213 has 4 electrical current measuring ports (4 channels), and is used as same
as MPM-211. The MPM-215 MM has 4 optical power measuring ports (4
channels) and enables optical power measurement for each port with a high
dynamic range of 60 dB or more. However, the MPM-215 cannot be used as
same as other modules (MPM-211/212/213) and it does not support the
measurement range switching function. The MPM-210H doesn’t have front
panel nor display window but it can be easily operated by remote control. The
MPM-210H is controllable by using GPIB, LAN, RS232 communication and users
can interlock the system with other system (santec Tunable Laser, TSL series
and Polarization Controller, PCU series) and operate it for measuring PDL and
IL. Commands for controlling the MPM-210H are listed and described in section
5.5.

・Dangerous voltages, capable of causing injury or death, are present in this
instrument. Use extreme caution whenever the instrument covers are
removed. Do not remove the covers while the unit is plugged into a live
outlet.
・To avoid electric shock, the power cord protective ground conductor must be
connected to ground.
・No user serviceable part exists in this instrument. Refer all services to
qualified personnel.
・Before using this instrument, be sure to read through operation manual and
data sheets to ensure correct operations. Contact SANTEC to obtain service
support and do not install substitute parts or perform any unauthorized
modifications to this instrument.
4.2. Environment

4.3. Line Voltage Selection
This Instrument complies with overvoltage category II and can operate from
any single-phase AC power source that supplies 100 - 120V/ 200 - 240V at a
frequency at 50/60Hz. The power consumption is 50VA max.
4.4. Line Fuse
The fuse used by this instrument is T1.6A/ 250VAC (100 - 120V/ 200 - 240V).
4.5. Line Cord
・This instrument has three-wire power cord for connection to the power
source and to a protective ground.
・The exposed metal chassis of the instrument is connected to ground via the
power line cord to protect against electrical shock. Always use a socket outlet
that has a properly connected protective ground.
This product is grounded by the ground line in the supplied power cable.
This product must be properly grounded to avoid electrical shock and other
dangers. Please make sure that this product is properly grounded to avoid
electrical shock. In addition, please place this product in a location that allows
the user to easily unplug the power cable, in case of any device malfunction.
4.6. Zeroing option (To remove electrical offsets)
The MPM-210H (Optical Power Meters) measures optical power by converting
optical power to electrical power of photo detector, and then measuring electrical
power. If there is electrical offsets, the MPM-210H may not allow you to measure
optical power with accuracy. So, we recommend you performing the zeroing
whenever tuning on this instrument or before you need an important
measurement. Please refer to “5.5.3. Measurement-related commands” for the
detail.
4.7. Maximum input optical power
The maximum input power that can be applied to any port of the power meter is
16dBm. Applying more than the specified power might damage the power meter!

4.8. Inserting a module
The MPM-210H (Main frame) is used to insert some modules (MPM-211/MPM-
212/MPM-213/MPM-215). With the power off, please insert the module while
paying attention to the orientation of the module. After inserting it, fix it with the
knurled screw on the top of the module. The MPM-210H cannot allow you to
insert any previous modules (MPM-10/MPM-20).
Insertion of an incompatible module may cause equipment failure. Moreover,
please fix the module using knurled screw after inserting each module.

5.Remote Control
Before inserting and extracting the connectors for the communication
cables, make sure to turn off power to the device to avoid damaging the
device.
The MPM-210H exchanges information with controller by using GPIB, TCPIP or
RS232 communication.
5.1. GPIB Communication
The MPM-210H supports IEEE488 interface. When receiving a command, it uses
EOI but not EOS. When sending a command, it uses EOI and EOS<CR>.
Default value of GPIB Address is 16.
Connect the 24-pin GPIB cable to the GPIB connector on the rear panel. The
total extension of the connected cable shall be 20 m or less. The cable length
between each device must be 2 m or less. At most, 15 devices can be
connected.
Do not disconnect or connect a cable from and to devices connected with
GP-IB cable, do not short-circuit the connector, and do not turn ON/OFF the
devices. Otherwise, actions may be stopped or errors may occur, causing a
failure. In the event of such failure, reset all the connected devices, and
then activate the system once again. When configuring a system, remove
the unused device or unnecessary cable and return to the original setup.
