MG3690B
RF/Microwave Signal Generator, 0.1 Hz to 70 GHz/325 GHz
Introduction
The MG3690B is the “ideal microwave signal generator” because it offers unsurpassed frequency coverage, leveled output
power, spectral purity, switching speed, modulation performance, size, upgradeability, reliability, and service. Our signal
generators are configurable for a broad range of applications from R&D to manufacturing and depot repair. Anritsu provides
you a total solution including proven reliability and standard 3 year warranty plus pre- and post-sale support that is the best
in the industry.
The Ideal Signal Generator

generator for 25 ± 10°C. Typical specifications describe expected, but not warranted,
performance based on sample testing.

Option 5 10 MHz to 2 GHz Model No. Dependent
Option 22 0.1 Hz to 10 MHz Model No. Dependent
* Operational to 70 GHz
Options 4 and 5: Frequency extension down to 10 MHz
Two options are available to extend the 2 GHz low end frequency limit of the base
models down to 10 MHz. Option 4 uses a digital down-converter (DDC) with successive
divide-by-two circuitry. It offers the best phase noise performance of the two choices, at
the expense of some analog performance <500 MHz. In that range, analog sweep mode
is not available, and pulse modulation performance is specified as typical. In addition,
frequency and phase modulation mod index is scaled by the division ratio of each band
of the DDC. Option 5 maintains all analog performance by using a heterodyne mixing
down-converter, but does not improve phase noise performance.
Option 22: Frequency extension down to DC
If frequency coverage down to 0.1 Hz is desired, Option 22 can be added with either
Option 4 or 5. Option 22 uses Direct Digital Synthesis (DDS) for CW and Step Sweep
modes of operation. Modulation and analog sweep are not available in the DDS band.
Frequency resolution <10 MHz is 0.02 Hz. Output power across the complete instrument
frequency range is degraded by 2 dB.

including lock time. V
ariable from 20 ms to 99 seconds.
Analog Sweep Mode (Option 6)
Sweep Width: Independently selected from 1 MHz to full frequency range. With Option
4, Digital Down Converter, Analog sweep is only available ≥500 MHz. Analog sweep is
not available <10 MHz with Option 22.

for Sweep Speeds of ≤50 MHz/ms (typical)
Sweep Time Range: 30 ms to 99 seconds
Alternate Sweep Mode
Sweeps alternately in step sweep between any two sweep ranges. Each sweep range
may be associated with a power level.

List Sweep Mode
Under GPIB control or via the front panel, up to 4 tables with 2000 non-sequential
frequency/power sets can be stored and then addressed as a phase-locked step sweep.
One table of 2000 points is stored in non-volatile memory, all other tables are stored in
volatile memory.

General
Stored Setups: Stores front panel settings and nine additional front-panel setups in a
non-volatile RAM. A system menu allows saving and recalling of instrument setups.
Whenever the instrument is turned on, control settings come on at the same functions
and values existing when the instrument was turned off.
Memory Sequencing Input: Accepts a TTL low-level signal to sequence through ten
stored setups.
Self-Test: Instrument self-test is performed when Self-Test soft-key is selected. If an
error is detected, an error message is displayed in a window on the LCD identifying the
probable cause and remedy
Secure Mode: Disables all frequency and power level state displays. Stored setups
saved in secure mode remain secured when recalled. Mode selectable from a system
menu and via GPIB.
Parameter Entry: Instrument-controlled parameters can be entered in three ways:
keypad, rotary data knob, or the ∧ and ∨ touch pads of the cursor-control key. The
keypad is used to enter new parameter values; the rotary data knob and the cursorcontrol key are used to edit existing parameter values.
cursor-control key move the cursor left and right one digit under the open parameter
The rotary data knob or the ∧ and ∨ touch pads will increment or decrement the digit
position over the cursor
dwell time, and number of steps. Keypad entries are terminated by pressing the
appropriate soft key. Edits are terminated by exiting the edit menu.
Reset: Returns all instrument parameters to predefined default states or values.
Any
Master/Slave Operation: Allows two output signals to be swept with a user-selected
frequency of
connections. Requires a Master/Slave Interface Cable Set (Part No. ND36329).
User Level Flatness Correction: Allows user to calibrate out path loss due to external
switching and cables via entered power table from a GPIB power meter or calculated
data. When user level correction is activated, entered power levels are delivered at the
point where calibration was performed. Supported power meters are Anritsu ML2437A,
ML2438A, and ML4803A
available with up to 801 points/table.
Warm Up Time:
From Standby: 30 minutes.
From Cold Start (0 deg C): 120 hours to achieve specified frequency stability with
Instruments disconnected from AC line power for more than 72 hours require
30 days to return to specified frequency stability with aging.
Power: 85-264 Vac, 48-440 Hz, 250 VA maximum
Standby: With ac line power connected, unit is placed in standby when front panel
power switch is released from the OPERATE position.
