Measurement Corrections
Corrections both input output necessary accurate measurements. MAX2116/ MAX2118 boards, F-connectors impedance) mounted RFIN port. test equipment, adapter needed. Thus, input power must adjusted compensate adapter loss (typically 5.7dB "min-loss" pad). baseband output ports, there resistors series with output pins, which lead 26.4dB loss test equipment used. Therefore, MAX2116 kit, full-scale output (800mVP-P) corresponds -24.4dBm. MAX2118 kit, when full-scale output (1VP-P, differential) corresponds -28.4dBm each output port, while fullscale output (590mVP-P, differential) corresponds -33dBm each output port. When connecting test equipment, always ensure that blocking used that output bias networks disrupted. Note MAX2118: power levels specified this description refer single-ended measurements. Open MAX2116/MAX2118 software. software opens either MAX2116 MAX2118 mode. change appropriate part under Option Menu: "Select EVkit type: MAX2116 MAX2118". Click Synthesizer configure following: Divider (This sets comparison frequency 1MHz when using on-board 4MHz crystal) Calibrate VCOs clicking "VCO Cal" button. Check "Auto Select" "Auto Band Select" (This allows software pick appropriate divider (div select appropriate entered frequency.) Enter desired frequency Select Base following: Gain Control (max baseband gain) Divide FDAC (max baseband filter bandwidth) using MAX2118, select desired baseband peak-to-peak output under "Drive Level" (1VP-P 590mVP-P). generator's output power approximately -65dBm. Activate generator's output select desired input frequency that generator's frequency 5MHz higher than frequency Step This creates single 5MHz tone baseband output ports. spectrum analyzer: 5MHz, Span 200kHz, 1kHz, 1kHz. using oscilloscope, observe tone 5MHz. Adjust power obtain proper output levels specified "Measurement Corrections" section this procedure. Analog Gain Control (GC1) Test: Adjust power supply connected (GC1) 0.75V (max gain). Ensure that baseband gain setting decimal (max baseband gain). signal generator's frequency 5MHz higher than desired frequency input power -65dBm. (The signal generator power might need adjusted produce full-scale baseband output level.)

Connections Setup
This section provides step-by-step guide operating testing device's function. turn power signal generators until connections made: Verify that jumpers place. Connect using parallel cable. Connect power supply (through ammeter, desired) terminals kit. current limit 300mA. turn supply. Connect second power supply 0.75V (max gain) (TP7). current limit 10mA. turn supply. Connect signal generator RFIN connector. adapter necessary. turn generator's output. Connect output spectrum analyzer digital oscilloscope. using spectrum analyzer oscilloscope mode, insert block protect analyzer from damage. Turn supplies. supply should read approximately 190mA. 0.75V supply should less than 1mA.

delta marker desired tone increase voltage. gain delta greater than 60dB. Digital Gain Control (GC2) Test: Adjust power supply connected 0.75V (max gain). baseband gain control (max baseband gain). signal generator's frequency 5MHz higher than desired frequency input power -65dBm. (The signal generator power might need adjusted produce full-scale baseband output level.) delta marker desired tone increase baseband gain control gain delta larger than 20dB. Lowpass Filters Test: Adjust power supply connected 0.75V decimal (max baseband gain). generator -65dBm 10MHz higher than desired frequency. spectrum analyzer measure from 50MHz delta marker desired tone. (Adjust level full-scale baseband output level.) While monitoring 10MHz tone spectrum analyzer, decrease FDAC. Note decrease filter-noise-floor bandwidth. When computed equals 10MHz, desired tone attenuated more than 1dB.
Layout Issues
good board essential part circuit design. board serve guide laying board using MAX2116/MAX2118. Keep traces carrying signals short possible minimize radiation insertion loss. impedance control signal traces. node board should have decoupling capacitors closest ground.
