The DS-7210 portable telemetry signal simulator is a handheld, battery-powered, synthesized test signal source designed to tune from 2200 to 2300 MHz in 500-kHz steps. Its output-power level can be set from +10 to 20 dBm in 1-dB increments. The instrument allows a pulse-code-modulated (PCM) data stream to be selected with various data rates from 10 kB/s to 10 mB/s. The signal simulator includes a USB port for connectivity to an external personal computer, thereby allowing the import of custom modulation formats. The simulator can be supplied with an optional low-gain omnidirectional antenna or a directional antenna with 6-dBi gain.
