Signal Generator Overview Preliminary
Modes of Operation Preliminar
Modes of Operation
Depending on the model and installed options, the Agilent MXG signal generator provides up to four
basic modes of operation: continuous wave (CW), swept signal, analog modulation, and digital
modulation.
Continuous Wave
In this mode, the signal generator produces a continuous wave signal. The signal generator is set to
a single frequency and power level. Both the N5161A/81A and N5162A/82A can produce a CW signal.
Swept Signal
In this mode, the signal generator sweeps over a range of frequencies and/or power levels. Both the
N5161A/81A and N5162A/82A provide list and step sweep functionality.
Analog Modulation
In this mode, the signal generator modulates a CW signal with an analog signal. The analog
modulation types available depend on the installed options.
Option UNT provides AM, FM, and ΦM modulations. Some of these modulations can be used together.
NOTE The Mod On/Off hardkey and LED functionality are only valid for MXGs with Option UNT
installed.
Refer to 14. Mod On/Off and LED.
Options UNU and UNW provide standard and narrow pulse modulation capability, respectively.
Digital Modulation (N5162A/82A with Options 651, 652, or 654 Only)
NOTE The internal baseband generator speed upgrade Options 670, 671, and 672 are option
In this mode, the signal generator modulates a CW signal with a arbitrary I/Q waveform. I/Q
modulation is only available on the N5162A/82A. An internal baseband generator (Option 651, 652, or
654) adds the following digital modulation formats:
• Custom Arb Waveform Generator mode can produce a single–modulated carrier or
• Multitone mode produces up to 64 continuous wave signals (or tones). Like the Two Tone mode,
4 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
upgrades that require Option 651 and 652 to have been loaded at the factory (refer to the
Data Sheet for more information). Any references to 651, 652, or 654 are inclusive of 671,
672, and 674.
multiple–modulated carriers. Each modulated carrier waveform must be calculated and generated
before it can be output; this signal generation occurs on the internal baseband generator. Once a
waveform has been created, it can be stored and recalled, which enables repeatable playback of
test signals. To learn more, refer to “Using the Arbitrary Waveform Generator” on page 261.
the frequency spacing between the signals and the amplitudes are adjustable. To learn more, refer

Preliminary Signal Generator Overview
• Two–tone mode produces two separate continuous wave signals (or tones). The frequency spacing
between the signals and the amplitudes are adjustable. To learn more, refer to Chapter 12,
"Multitone and Two–Tone Waveforms (Option 430)".
• Dual ARB mode is used to control the playback sequence of waveform segments that have been
written into the ARB memory located on the internal baseband generator. These waveforms can
be generated by the internal baseband generator using the Custom Arb Waveform Generator
mode, or downloaded through a remote interface into the ARB memory. To learn more, refer to
“Dual ARB Player” on page 132.

• A 400ms duty cycle indicates the instrument has been placed into LAN Identify mode. (Refer to
:INPut:LAN[:SET]:IDENtifier command).
• If the LED is solidly lit, the LAN is up and functional.
• If the LED fails to function, refer to the Service Guide.
4. 1588 LED
The 1588 LED indicates when the instrument is locked to an external 1588 clock.
• If the 1588 green LED is on, a 1588 signal has been detected on the TRIG OUT BNC on the rear
panel.
• If the 1588 green LED is off, no 1588 signal is detected on the TRIG OUT BNC on the rear panel.
• If the LED fails to function, refer to the Service Guide.
5. ERROR LED
The ERROR LED indicates when there are unread errors in the error queue.
• If Auto reboot is disabled, the LED will blink when an exception occurs during power up.
• If the LED fails to function, refer to the Service Guide.
6. LAN Reset Hardkey
NOTE This hardkey is enabled for fail–safe and diagnostic mode and should rarely be used.
The LAN Reset is used to access the diagnostics mode during power up.
• Refer to the SCPI Command Reference for equivalent remote commands.

N5161A/62A MXG ATE – Web Enabled Display
The MXG ATE only has display information available through a LAN connection to the Web Server

Annunciators
NOTE On the N5161A/62A, the following listing of annunciators are only displayed and visible
through the Web–Enabled MXG. Refer to Programming Guide, “Using the Web Browser”.
Annunciators show the status of some of the signal generator functions, and indicate error
conditions. An annunciator position may be used by more than one annunciator; in this case, only
one of the functions sharing a given position can be active at a given time.
This annunciator appears when...
ΦM Phase modula tion is on. If you tur n frequency modulation on, the FM annunciator replaces ΦM.
ARB The ARB generator is on.
ALC OFF The ALC circuit is disabled. The UNLEVEL annunciator appears in the same position if the ALC is enabled and
AM Amplitude modulation is on.
ARMED A sweep has been initiated and the signal generator is waiting for the sweep trigger event.

1. AC Power Receptacle
The AC power cord receptacle accepts a three–pronged AC power cord that is supplied with the
signal generator. For details on line setting requirements and the power cord, see the
Installation Guide.
CAUTION To avoid the loss of data, GPIB settings, or current user instrument states that have not
been permanently saved to non- volatile memory, the MXG should always be powered
down either via the MXG's front panel power button or the appropriate SCPI command.
MXG's installed in rack systems and powered down with the system rack power switch
rather than the MXG's front panel switch display a Error -310 due to the MXG not being
powered down correctly.

Connector female BNC
Can drive 2 kΩ.
Signal Voltage range: 0 to +10 V, regardless of sweep width
In swept mode: beginning of sweep = 0 V; end of sweep = +10 V
In CW mode: no output
This is a multiple use connector. For signal routing selections, see pages 50 and 121.
