The instrument displays a warning if the time or temperature limits are exceeded. Static EVM and phase error measured with residual carrier magnitude removed. IQ Image Suppression At 10 kHz modulation frequency Typically <-50 dBc @ 10 kHz Linearity (See linearity chart over page) Adjacent Channel Power (ACP), in ACP mode for continuous and discontinuous signals at RF output levels 0 dBm, over the temperature range 23°C ± 5°C RF BURST CONTROL A digital control bit is used to generate an analog ramp (up or down) of the RF output. The Burst Gate control signal can either be generated internally as part of the optional internal base-band source, or provided externally by the user on the rear panel connector. When internally generated, the Burst Gate control signal appears on the rear panel auxiliary connector that then serves as an output. On/Off Ratio For the temperature range 23°C ± 5°C >90 dB for carriers 3 GHz >80 dB for carriers 4 GHz >65 dB for carriers 6 GHz Ramp Profile Rise and fall time after the L-H and H-L transitions of the burst control bit respectively can be defined by the user from 10 ìs to 999 ìs in 0.1 ìs steps. Burst Gate control input is a TTL level (HCT), 50 Ù impedance BNC input on the rear panel. RF ramp can be adjusted in time by ±50 ìs in increments of 0.1 ìs with respect to the trigger event. RF BURST ATTENUATION CONTROL A digital attenuation control bit (in conjunction with the ramp control bit) is used to decrease the RF level from the set level to an alternative level during burst modulation. The Burst Attenuation Trigger signal can be provided internally as part of the optional dual arbitrary waveform generator (ARB), or externally on a rear panel connector. When internally generated, the Burst Attenuation Trigger control signal appears on the rear panel auxiliary connector that then serves as an output. Attenuation range available is 0 to 70 dB. Burst Attenuation Trigger control is a TTL level (HCT), 50 Ù impedance signal available on the rear panel Auxiliary connector. RF burst attenuation requires Electronic Attenuator Opt 003.
