Coupling between Channels
Introduction
3.9.1
Selecting a Pulse
waveform
Selecting the
Frequency and
Delay
This example shows how the two channels can be coupled, so that the
instrument behaves like a 2 channel instrument with only one timebase. In
this mode, the frequency and phase of both the channels are locked. Locking
the output frequency and phase of both channels does have a noticeable
effect on most of the major operations modes. Therefore, as a result of
coupling, the output function, and all other parameters like, burst, sweep,
and modulation are also kept identical on both channels.
Refer to the 81150A and 81160A User Guide for more information.
Let’s set different values for different parameters on both channels
one-by-one, and enable coupling.
Settings for Channel 1
To set the operating mode and trigger mode as required, do the following:
 Ensure that the Ch 1 key is selected.
 Before setting any values, press the Store/Recall key and press the

Power Requirements
Caution
Before applying AC line power to the instrument, ensure that the correct
power cable is fitted.
Note
When the front panel switch is off, the Mainframe is in “Standby” mode.
Disconnection from the AC Line Power is accomplished only by
disconnecting the power cord. Please make sure that the power cord is
easily identifiable and can quickly be reached by the operator.
The instrument can operate from any single-phase AC power source
supplying 100−240 V in the frequency range from 50 to 60 Hz, or 100−120 V
at 400 Hz. The maximum power consumption is 180 VA with all options
installed. When the instrument is switched on the power supply adapts
automatically to the applied AC power (Auto Selection) and monitors the AC
power range during operation.
Installation and Maintenance
4.3
Ventilation Requirements
Introduction
4.3.1
The instrument is fitted with three cooling fans. Make sure that there is
adequate clearance of 80 mm at the rear and 25 mm on both sides to ensure
adequate air flow. If the air flow is restricted the internal operating
temperature will be higher, reducing the instrument's reliability or causing
the instrument's thermal-protection circuits to automatically switch off the
instrument.
Thermal Protection
Overheating
Detection
The instrument monitors its internal temperature. If the temperature
exceeds approximately 80°C the power supply is switched off. The
instrument will not turn on automatically if the temperature is decreasing
again.
Fan Failure
If a fan is broken or prevented from operating by a blockage the temperature
will increase. When the temperature exceeds approximately 80°C the
overheating detection switches off the instrument for safety reasons. For
reliability it is recommended to send instruments with broken or defective
fans immediately to Agilent Service for repair.
