Synthesized RF Signal Generator
Informatie
The 6062A Synthesized RF Signal Generator (referred to as
the Generator or instrument) is a fully-programmable,
precision, synthesized signal Generator. The Generator is
designed for applications that require good modulation,
frequency accuracy, and output level performance with
moderate spectral purity. It is well suited for testing a
wide variety of RF components and systems including filters,
amplifiers, mixers, and radios, particularly on-channel
radio testing.
Generator DESCRIPTION
Fundamental features of the Generator are as follows:
• 0.10- to 1050-MHz frequency range in 10-Hz steps
• 1050- to 2100-MHz frequency range in 20-Hz steps
• +16 to -137-dBm level range in 0.1-dB steps from 0.10 to
1050 MHz
• +13 to -137~dBm level range in 0,1-dB steps from 1050 to
2100 MHz
• AM, FM, 4>M, and Pulse, internal or external
• Internal 400- and 1000-Hz modulation Oscillator
• Relative frequency and amplitude
• Volts/dBm conversion
• Store/recall memory
• instrument (or controller) prompted Software compensation
• Master/slave for frequency, amplitude, and modulation
functions (IEEE-488 Interface controlled.)
• Fluorescent display
• S^-inches high, rack mountable 1 -6. Controller Functions
The Generator’s microprocessor controls all operator
Interface functions, performs background operations such as
status checks, and updates (strobes) the front panel
displays. Whether the operator is using local control with
the front panel, or remote control with the IEEE-488
Interface, the microprocessor provides self test and
diagnostic capability. Economical instrument performance is
achieved by using Software compensation and
accuracy-enhancement circuitry.
1-7. LOCAL CONTROL
The value of the Basic output parameters of the Generator
(i.e., amplitude, frequency, or modulation) can be
controlled in three ways:
• Direct numeric entry
• Incrementing or decrementing the bright digit
• Step-up or step-down entry where the operator can program
the step size via the front panel
Other controls provide selection of the modulation control,
internal/'external frequency reference, instrument status,
and special function modes. Refer to Tables 2-1 and 2-2 for
a more complete discussion.
1-8. DISPLAY FIELD
The programmed values of modulation, frequency, and
amplitude are displayed in the three display fields. In
addition, when the operator presses the [STATUS] key, uncal
and reject entry codes are displayed. The display also
prompts the operator during the Software compensation
procedures.
1 -9. REMOTE-CONTROL PROGRAMMING
The IEEE-488 Interface allows the Generator to be remotely
controlled with any IEEE-488 bus controller. The operator
can also use the instrument on the IEEE-488 bus without a
controller in a listen-only or talk-only mode by selecting
the appropriate Generator rear panel IEEE-488 switch settings.
All instrument controls can be controlled remotely except
the POWER ON/ OFF and the rear panel REF INT/EXT switches.
The IEEE-488 Interface provides additional commands not
available with local control, such as data transfer and
individual control of internal I/O control bits.
The IEEE-488 Interface allows two Generators to track
amplitude, frequency, or modulation in a master/ slave
configuration when the operator uses the front panel step-up
and step-down entries on one of the instruments. For
instance, frequency tracking is convenient for- tests
involving mixers, and amplitude tracking is useful for
two-tone intermodulation testing.
1-10. Frequency
The specified frequency range is 0.10 to 2100 MHz. The
frequency is synthesized from a 10-MHz reference and
provides an output resolution of 10 Hz from 0.10 to 1050
MHz, and 20 Hz from 1050 to 2100 MHz. The relative frequency
mode allows the operator to program the frequency in
relation to a center frequency or an offset frequency. This
is convenient for testing filters and mixers. The output
frequency stability and accuracy depends on the reference,
whether that reference is internal or external.
1-11. Reference
The internal frequency reference is a 10-M Hz ambient
crystal Oscillator. If Option -130 High Stability Reference
or Option -132 Medium Stability Reference is installed, the
internal Oscillator is locked to the option Oscillator.
With the REF I NT / EXT switch set to EXT, the Generator can
be operated from an external 1 -, 2-, 2.5-, 5-, or 10-MHz,
0.3 to 4V peak-to-peak sine or square-wave reference applied
to the REF IN connector. In either position of the REF
INT/EXT switch, the selected reference is available as a
10-MHz signal at the rear panel 10 MHz OUT connector.
1-12. Amplitude
The Generator has two specified signal level ranges:
+ 16 to -137 dBm (1.4 IV to 0.1 fjY) over a frequency range
of 0.10 to 1050 MHz + 13 to -137 dBm (IV to 0.033 //V) over
a frequency range of 1050 to 2100 MHz.
The programming limits are +17 and -147.4 dBm, which
correspond to limits of 1.58V to 0.01 fjV. The level entry
can be in dBm or volts, or it can be converted from one to
the other. The relative amplitude mode allows the operatorio
account for cascaded gain or loss by displaying the level
relative to the initial setting.
1-13. Modulation
The Generator has internal and external amplitude,
frequency, phase, and pulse modulation capabilities. The
internal modulation Oscillator is selectable between 400 and
1000 Hz. AM depths ofO to 99%are available in l%steps. FM
deviation ranges of I, 10, I00,and 400 kHz are available in
steps of I, IG, 100 Hz, and I kHz, respectively. <£M
deviation ranges of OTO, I.0, i0.0, and 40.0 radians (rad)
are available in steps of 0,001, 0.01, 0.1, and 0, l
radians, respectively. The internal Pulse duty cycle is
approximately 50%. External Pulse allows rates from dc up to
16 MHz,, and duty cycles from 0 to 100%.
