This section explains the installation position of the mainframe and how to turn on the power.

2.1.1 Environmental Conditions of Installation Site

The MP1861A operates in the temperature range from 15 to 35°C. Avoid using it under any of the following environment conditions that may cause failure.

•

Strong vibrations

•

High humidity or dust

•

Direct sunlight

•

Chemically active gases

•

Substantial temperature changes

Note:

Condensation may form inside of the MP1861A if it is moved to a warm location after operating for a long time in a cool location. In such a case, be sure to wait until the MP1861A becomes completely dry before turning on the power. Doing so with condensation present may cause a short circuit and damage the MP1861A.

2.1.2 Clearance from Fan

A cooling fan is provided on the side of the MP1861A. Install the MP1861A at least 10 cm away from walls, peripheral devices, or the like to prevent blockage of ventilation. Insufficient ventilation may cause the internal temperature to rise, resulting in failure.

become charged as a capacitor. Use any metal to

discharge the outer conductor and core before use.

Never open the MP1861A. If you open it and the

MP1861A has failed or sufficient performance cannot

be obtained, we may decline to repair the MP1861A.

The MP1861A has many important circuits and parts

including hybrid ICs. These parts are extremely

sensitive to static electric charges, so never open the

case of the MP1861A.

The hybrid ICs used in the MP1861A are sealed in

airtight containers; never open them. If you open it and

the MP1861A has failed or sufficient performance

cannot be obtained, we may decline to repair the

MP1861A.

To protect the MP1861A from e being damaged by

static electricity, be sure to observe the following:

• Spread a conductive sheet on a workbench.

• Wear a wrist strap connected to the conductive

sheet or the frame ground of MP1861A

Before Use

•

CAUTION

When connecting an external device such as a Bias-T

to the output connectors of this equipment (PPG or

MUX), if the output signal includes any DC voltage,

variations in the output of the DC power supply or load

may change the level of the output signal, risking

damage to the internal circuits. Note the following

precautions when using this equipment:

Do not connect or disconnect any external devices

while DC voltage is impressed.

Only switch DC power sources ON and OFF when all

equipment connections have been completed.

Measurement Preparation 1:

1. Connect all equipment.

2. Set the DC power supply output to ON.

3. Set the equipment output to ON and complete

measurement.

Measurement Preparation 2:

1. Set the equipment output to OFF.

2. Set the DC power supply output to OFF.

3. Disconnect the equipment, or change the DUT

connections.

Since even unforeseen fluctuations in DC voltage and

load (open or short circuits at the equipment output

side and changes caused by using a high-frequency

probe, etc.) can damage the DUT and equipment, we

recommend connecting a 50–ohm resistance in series

with the DC terminal of the Bias-T to prevent risk of

damage.
