n		Results Returned

not specified or		Returns the following comma-separated scalar results:
n=1		1. Sample time is a floating point number representing the time between

		samples when using the trace queries (n=0,2,etc).
		2. Mean power is the mean power (in dBm). This is either the power
		across the entire trace, or the power between markers if the markers are
		enabled. If averaging is on, the power is for the latest acquisition.
		3. Mean power averaged is the power (in dBm) for N averages, if
		averaging is on. This is either the power across the entire trace, or the
		power between markers if the markers are enabled. If averaging is on,
		the power is for the latest acquisition. If averaging is off, the value of the
		mean power averaged is the same as the value of the mean power.
		4. Number of samples is the number of data points in the captured
		signal. This number is useful when performing a query on the signal
		(i.e. when n=0,2,etc.).
		5. Peak-to-mean ratio has units of dB. This is the ratio of the maximum
		signal level to the mean power. Valid values are only obtained with
		averaging turned off. If averaging is on, the peak-to-mean ratio is
		calculated using the highest peak value, rather than the displayed
		average peak value.
		6. Maximum value is the maximum of the most recently acquired data
		(in dBm).
		7. Minimum value is the minimum of the most recently acquired data (in
		dBm).

2		Returns comma-separated trace points of the entire captured trace data.
		These data points are floating point numbers representing the power of the
		signal (in dBm). There are N data points, where N is the number of
		samples. The period between the samples is defined by the sample time.

3, cdma2000,		Returns comma-separated magnitude values of the time data in Volts peak.
W-CDMA, Basic
modes only

4, Option B7C		Returns comma-separated values of phase in degrees.

W-CDMA, Basic

5, Option B7C		In input modes other than Ionly and Qonly returns comma-separated
with cdma2000,		values of I and Q trace data in Volts. The values are in pairs with the I
W-CDMA, Basic		value first. In Ionly and Qonly the data retured is comma-separated values
modes only		of the I data or the Q data.
