    <NR2> LIMit:FREQuency:LOW? This command queries the lower frequency limit of the power source. On the 2001RP-AV, the frequency range may have been factory configured to a fixed single value. In this case, the High and Low frequency limits will be set to the same value and both queries will return the same number.
  • Page 107 If the voltage limit value is less than 201 volt, the 2001RP is configured for single voltage range operation. If a value above 200 volt is returned, the 2001RP has a high and a low voltage range. On dual range configurations, the maximum voltage in the high range is returned and this value must be even.
