69A, 68B series
10 MHz to 65 GHz

GPIB
A microwave synthesizer for any application

Anritsu’s El Toro microwave synthesizers present 120 models, providing you the right synthesizer for your LO duty, component analysis, signal simulation, or A.T.E. applications. The 69A family, with thelowest Single Sideband (SSB) phase noise available, provides theultimate performance at moderate cost. And includes models with
unprecedented 0.01 to 65 GHz frequency coverage.

Features• 120 models for perfect fit to any application• Ultra-low SSB phase noise; –100 dBc at 10 kHz offset from 10 GHz• 0.01 to 65 GHz frequency coverage in a single coaxial output• Waveguide extensions to 110 GHz• Economical upgrades• +17 dBm maximum power, –125 dBm minimum power• Internal AM, FM, øM, pulse modulation• User down-loaded complex modulation
Applications• CW stimulus

The 69000A/68000B Synthesized CW Generators feature 10 MHz to
65 GHz frequency coverage. CW or step sweep, low SSB phasenoise and spurious signals, output levels to +17 dBm, and optional
0.1 Hz resolution combine to make these sources ideal for local oscillator replacement applications. To meet requirements that expand
over time, economical upgrades are available to any higher performing model. For the most demanding CW requirements, the69000A and 68000B provide the ultimate in performance.

200• Swept measurements
The 69100A/68100B Synthesized Sweep Generators feature 10
MHz to 65 GHz analog, step, and manual sweep capability. Output
levels to +17 dBm, and optional 0.1 Hz resolution are available atprices comparable to CW only sources. To meet requirements that
expand over time, economical upgrades are available to any higher
performing model. Features, performance, and value combine to
make the 69100A and 68100B the optimum sources for your network
analysis and swept A.T.E. source applications.
• High performance modulation for signal simulation requirements
The 69200A/68200B Synthesized Signal Generators provide AM
and FM via external modulating signals or internal arbitrary waveform generators. The internal generators offer 7 modulating waveforms, including Gaussian noise, as well as user-defined arbitrary
waveforms. Pulse modulation parameters can be set externally or by
the internal pulse generator. Doublet, triplet or quadruplet pulses
make RADAR blind spot testing easy. Simultaneous synchronized
modulations let you set complex signal scenarios across the entire
10 MHz to 65 GHz frequency range.
• Complete synthesized modulation and sweep capabilities forany signal requirement
The 69300A/68300B Synthesized Sweep/Signal Generators provide
all the capabilities of our CW generators, sweep generators and signal generators in a single package. The 69300A is the highest performance universal synthesized signal generator available today.

Emulations

The instrument responds to the published GPIB commands and responses of the models 6XX00-series
signal sources. When emulating another signal source, the instrument is limited to the capabilities,
mnemonics, and parameter resolutions of the emulated instrument.

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 nine stored setups. AUX I/O connector, rear panel

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.

Secure mode

Disables all frequency, power level, and modulation state displays. Stored setups saved in secure moderemain secured when recalled. Mode selectable from a system menu and GPIB

Reset

Returns instrument parameters to predefined default states or values. Any pending GPIB I/O is aborted.
Selectable from the system menu

Master/slave operation

Allows two 68X00B output signals to be swept with a user-selected frequency offset. One 68X00B unit
controls the other via AUX I/O and SERIAL I/O connections. Requires MASTER/SAVE 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 aredelivered at the point where calibration was performed. Supported power meters are Anritsu ML4803A
and HP437B, 438A, and 70100A. Five user tables are available at up to 801 points/table

Warm up time (standard time base)
