Informatie

The 6060A.AN Synthesized Signal Generator (referred to as the Generator or instrument) is a fully-programmable, precision, synthesized signal Generator. In addition, an FM deviation meter is included. 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: 0.01-MHz to 520-MHz output frequency range in 10-Hz steps + 13-dBm to -127-dBm level range in 0. l-dB steps AM and FM, internal or external Internal 400-Hz and 1000-Hz modulation Oscillator FM Deviation Meter Relative frequency and amplitude Volts/dBm conversion Store/recall memory Master/slave for frequency, amplitude, and modulation step (IEEE-488 Interface controlled) Fluorescent display, 5 '/t-inches high, rack mountable (with optional kit) 1-5. Controller Functions The Controller microprocessor controls all operator Interface functions, performs background operations such as status checks, and updates (strobes) the front panel displays. Whether you are 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 1-6. LOCAL CONTROL The value of the basic 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 step size can be operator programmed Other controls provide selection of the POWER ON/OFF, RF OUTPUT ON/OFF, MODULATION ON/OFF, internal/external frequency reference, and STATUS. 1-7. DISPLAY FIELD The programmed values of modulation, frequency, and amplitude are displayed in the three display fields. When in the deviation meter mode, the measured deviation, frequency, and detector status are displayed in the three display fields. 1-8. REMOTE-CONTROL PROGRAMMING The IEEE-488 Interface allows the Generator to be remotely controlled with any IEEE-488 bus controller. The instrument can also be used 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 remotely controlled 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 using 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. 1-9. Frequency The specified frequency range is 0.01 to 520 MHz. The frequency is synthesized from a m.MH7 rpfprpnpp onrl r» r rn /1 /H pc on Aiitnnt ro c lliti nn rtf 1 A l-I 7 r 70 f ilia onti ro f ran uan/i r *V >'* lit 1 Wiv,« v.ivt Uiiu pi w v 1UVJ un i** I i VOU1U11U1I KJ1 1 J Hi, U VV1 LllW LUlll W II W Vj UCI range. The relative frequency mode allows the frequency to be programmed 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. 1-10. Reference The internal frequency reference is a 10-MHz ambient crystal oscillator. With the rear panel REF INT/EXT switch set to INT, the Generator output frequency is synthesized from the internal 10-MHz crystal Oscillator reference, and the internal Oscillator (timebase) TTL signal is available at the 10 MHz IN/OUT connector. ^CTO^^QQQaiSKrated from an external 10-MHz timebase by setting the rear panel REF INT/EXT switch to EXT and applying a TTL timebase signal to the 10 MHz IN/OUT connector. 1-11. Amplitude The Generator has a specified signal level range from + 13 to -127 dBm with programming limits of+ 19 and -147.4 dBm. This corresponds to specified terminated voltages of IV to 0.1 yuV and limits of 2V to 0.01 ¿iV, respectively. The maximum usable signal level is approximately + 15 dBm. The level entry can be in dBm or volts, or it can be converted from one to the other. In addition, the relative amplitude mode allows you to account for cascaded gain or loss, or to display the level (in dB) relative to 1 ¿tV or 1 mV. 1-12. Modulation Both internal and external amplitude modulation and frequency modulation capability is available. The internal modulation Oscillator is selectable between 400 Hz and 1000 Hz. AM depths of 0% to 99% are available in 1% steps. FM deviation ranges of 10 kHz, 100 kHz, and 500 kHz are available in steps of 10 Hz, 100 Hz, and 1 kHz, respectively. 1-13. Deviation Meter The deviation meter measures FM deviation in two ranges of 500 kHz and 50 kHz. Deviation measurements can be made over a frequency range of 30 to 500 MHz and a level range of 15 mV to 5V rms. The frequency, displayed in the frequency field, can be varied while making deviation meter measurements. The measured deviation is displayed in the modulation field and the detector status (± peak) is displayed in the amplitude field.
