INTRODUCTION The Wavetek Model 2410 is a dual microprocessor controlled, single-loop synthesized signal generator that covers the frequency range of 10 kHz to 1100 MHz. It has an output power level continuously adjustable from 4-13 dBm to -127 dBm. In addition to CW operation, it is capable of AM/FM operation from an internal or external source. The 2410 has a very broad 500 kHz to 1 MHz peak FM deviation over the majority of its operating range. Standard features include an exclusive AutoCal® selfcalibration function for frequency and amplitude, extensive user diagnostics, an automatic power up test sequence, and 16 nonvolatile memory locations to store front panel settings. A 10 MHz sine wave reference output is available at the rear panel. A talk/listen GPIB fully conforming to the IEEE-488 standard is standard for the Model 2410. Because it utilizes the minimum uniqueness concept, the 2410 is easily conformed to any ATE system. It is fully compatible with the entire Wavetek 2500 family of instruments. All operational controls are located on the front panel. Controls include keypad switches for entry of all RF output numeric parameters. A 4-key cursor provides increment/decrement entry of numeric data in digit steps, with any displayed digit selectable as the digit around which changes occur. Instrument settings and operational status are indicated on a two-line LCD display. The 2410 is a space-saving 3/4-rack size. (Two optional rack mount adaptor kits are available.) 1.1.1 FREQUENCY CHARACTERISTICS The carrier frequency may be set from 10 kHz to 1100 MHz with 10 Hz resolution and .00025% (2.5 ppm) accuracy. Frequency aging is <1 ppm/year. 1.1.2 MODULATION CHARACTERISTICS The instrument features both internal and external AM and FM capabilities. The internal modulation source may be set at a 400 or 1000 Hz rate. AM depth is specified from 0 to 100%. FM deviation can be set at peak values from 10 kHz to 1 MHz, depending upon the output frequency (see section 1.2.7.2). A TTL compatible sine or square wave at 5 MHz or 10 MHz may be used as an external reference input. Internal and external sources may be used simultaneously to produce complex modulation. 1.1.3 OUTPUT LEVEL CHARACTERISTICS The Model 2410 has an RF output range of +13 dBm to -127 dBm with an accuracy of ±1.5 dB of the actual measured level. Level resolution is .1 dB. Output level may be read in dBm, dBmV, mV, or µV. Reverse power protection to 50 watts is standard. 1.1.4 AutoCal®/DlAGNOSTICS The Model 2410 utilizes a unique Auto-Cal® routine to perform a quick and easy almost completely automatic self-calibration. The routine is software controlled, menu driven, and activated from the front panel. A variety of other menu driven diagnostic/control programming aids are standard with the 2410. 1.1.5 STORED SETTINGS Nonvolatile memory locations allow up to 16 complete front panel settings to be stored and recalled in any order. This storage permits fast and accurate recall of frequently used settings. The 2410 powers up with the same settings present when power was removed, except the RF output will be off. 1.1.6 ERROR INDICATORS The 2410 front panel display indicates the following error conditions: - An unlocked condition in the phase locked loop circuitry - An unleveled condition in the RF output leveler circuitry - A tripped RF circuit breaker - Modulation frequency reference error
