Introduction and Specifications
1-1. THE 6070A/6071A INSTRUCTION MANUAL SET
1-2. The John Fluke Models 6070A and 6071A RF Synthesized Signal Generators are
documentated by a set of four manuals: the 6070A/6071A Operator Manual, the
6070A/6071A Calibration Manual, the 6070A/6071A Service Manual, and the
6070A/607IA Schematic Manual (Figure 1-1). The 6070A/607iA Operator Manual
introduces the operator to the instrument; familiarizes the operator with all instrument
controls, connectors, and indicators; and presents detailed operating information and
procedures for both manual (local) and systems (remote) operation. The 6070A/607IA
Calibration Manual provides procedures for general maintenance, performance checks,
and calibration adjustments. The 6070A/6071A Service Manual contains a description
of the theory of operation, troubleshooting procedures, and a list of replaceable parts.
The 6070A/6071A Schematic Manual contains schematic digrams, wire lists,
interconnects diagrams, and an overall basic block diagram of the instrument.
1-3. The major difference between the two models is that the 6071A has twice the upper
frequency limit of the 6070A. Because of their similarity, most of the text in this manual
will apply to both models. Text that applies to just the 6070A or just the 6071A will be
identified as such.

1-6 THE 6070A/6071A SYNTHESIZED RF SIGNAL GENERATOR
1-7. The John Fluke Models 6070A and 6071A Synthesized RF Signal Generators are
designed for use in the calibration laboratory, engineering laboratory, or manufacturing
environments. Both models offer extensive modulation capabilities and use phase-locked
loop circuitry to generate fully synthesized signals with extremely low discrete spurious,
and phase noise. These versatile instruments are intended for both bench and systems use.
When the instrument is used in a system, all front panel control functions (except
POWER and MOD OUT level) can be controlled via an iEEE-488, 1978, interface.
1-8. Instrument parameters, such as output frequency and amplitude, can be
programmed to specific values or manually adjusted using the Edit Knob (large knob
near the lower right corner of the front panel). The Edit Knob is connected to a digital
rotary encoder to provide the same continuous manual adjustment capability
analog tuning control provides, but with the positive positioning of a digital control. I he
rotary encoder has 25 magnetic detent positions. The user can feel each position of the
Edit Knob.
1-9. The major difference between the two models is that the 6071A has twice the output
frequency of the 6070A. The output frequency of the 6070A can be selected within Hz

over a range from 200 kHz lo 519.999999 Mhz (520 MHz). The output frequency of the
6071A can be selected within 1 Hz from 200 kHz to 520 MHz and within 2 Hz from 520
MHz to 1039.999998 MHz (1040 MHz). Both models can produce frequencies outside of
the specified ranges, but the performance is not guaranteed.
1-10. The UNCAL annunciator will turn on to indicate that the instrument is operating
beyond specified ranges. The synthesized RF signal is available at the from panel RF
OUTPUT connector (if the 607XA-830 Rear Panel Output Option is installed, the RF
output is available at a rear panel Type N connector).
1-11. Internal frequency reference is a 10 MHz free air timebase (the 607XA-130 Oven
Reference Option is available for increased accuracy and stability). This 10 MHz
reference can also be phase locked to external references of 1, 2, 2.5, 5, or 10 MHz(0.3 to
4V peak-to-peak sine or square wave) input via a rear panel BNC connector (50 Ohm
input impedance, nominally). When an external reference is used, the shift from internal
to external is automatic. The 10 MHz reference signal (used as the internal instrument
reference) is available as a TTL signal at a rear panel REF OUT connector.
1-12. Below 520 MHz, output level can be selected with a resolution of 0.1 dB over the
range of + 19 to -140 dBm (2 V to22nV rms)inlo 50 Ohms. At 520 MHz or above, output
level can be selected with a resolution of 0.1 dB over the range of+13 to -140 dBm (I V to
22 nV rms). Selected level is displayed on the front panel in either dBm or volts (the
instrument will convert from one to the other if the units are changed). The internal
microprocessor automatically compensates output level for flatness and accuracy
although this automatic correction can be disabled (special function 81).
1-13. The RF output signal can be modulated in various combinations of amplitude
modulation (AM), frequency modulation (FM), or phase modulation (0M) from internal
sources, external sources, or a combination of internal and external sources. Table 1-1
lists all modulation combinations and the possible modulation sources for each
combination. Amplitude modulation depth can be selected with a resolution of 0.1 % over
the range of 0% to 99.9% (see the specifications for calibrated range). The frequency
modulation function allows the output frequency to be deviated while the output
frequency is still synthesized unless the DCFM Mode is selected. Maximum index of
modulation that can be selected for either FM or 0M depends upon the output frequency
and the modulation frequency selected. The internal modulation signal can be made
available at the MOD OUT connectors (front and rear panels). An external modulation
signal can be either ac or dc coupled through parallel connectors on the rear and front
panels (MOD IN connector, 600 Ohm nominal input impedance). External input
sensitivity is such that a 1 V peak input signal produces the calibrated modulation. The
list of specifications at the end of this section provides detailed information about the
modulation characteristics.
1-14. Up to 9 front panel setups can be stored in the internal memory of the standard
instrument, but these setups are lost when the instrument is turned off. The 607XA-570
Non-Volatile Memory Option provides 50 memory locations. Since this option is battery
powered, front panel setups stored in these 50 locations are not lost when the instrument
is turned off.
1-15. Three outputs are available for coordinating the activity of associated devices:
sweep analog output, penlift output, and output invalid output. The sweep analog output
is available at the front panel SWP OUT connector. This output steps from 0 to lOV as
the frequency is swept from the start frequency to the stop frequency. The size of the steps
depends upon the sweep width and the sweep increment selected. The penlift output is

available at a rear panel BNC connector. This output is a TTL signal that goes high
during a sweep retrace and stays high until the next sweep starts. The output valid signal is
available at a rear panel BNC connector. This output is a TTL signal that goes high when
output frequency, output amplitude, or modulation is potentially unsettled.
1-16. The 6070A or 6071A can operate from line voltages either between 90 to 132V ac
or between 180 to 264V ac at any frequency from 47 to 63 Hz. Section 3 of this manual
presents a procedure for switching between the two ranges of line voltage.
