Column Listing for Line 1
Column | Column Name | Element | Type | Dimension | Description |
---|---|---|---|---|---|
1 | Time | Time | Real Number or Text | Date | Time. |
2 | Xmtr Power1 | Xmtr Power1 | Real Number | Power | The RF power output of the transmitter as measured at the input to the antenna. This is a user selectable value. |
3 | Xmtr Gain1 | Xmtr Gain1 | Real Number | Ratio | The antenna gain of the transmitter which is dependent on the antenna type selected. For transmitter models that do not have an antenna model, this is a user defined value. For the simple source transmitter, 0 dB is reported since the simple source transmitter is modeled as an isotropic radiator. When using a Multibeam Transmitter with the Beam Selection Strategy set to Aggregate Active Beams, the Xmtr Gain element represents an effective (not aggregate) gain that weighs the contribution of each beam in the link direction according to its transmitted power. |
4 | EIRP1 | EIRP1 | Real Number | Power | The effective isotropic radiated power in the link direction. This value is the product of the transmitter power and the transmitter gain in the link direction with the inclusion of user defined post transmit gains and losses. |
5 | Prop Loss1 | Prop Loss1 | Real Number | Ratio | The total propagation loss computed across all enabled propagation models. |
6 | Rcvd. Frequency1 | Rcvd. Frequency1 | Real Number | Frequency | The received frequency is the frequency that the receiver is tuned to in order to communicate with the transmitter. This frequency may be auto-tracked or entered by the user in the receiver properties. |
7 | Rcvd. Iso. Power1 | Rcvd. Iso. Power1 | Real Number | Power | Received isotropic power is the power at the receiver before the pre-receive gains/losses and the receiver antenna gain added (in dBW). It is equal to the EIRP with all the channel losses as well as the bandwidth overlap applied. |
8 | Flux Density1 | Flux Density1 | Real Number | PowerFluxDensity | The power from the desired transmitter crossing a unit area normal to the direction of wave propagation. |
9 | g/T1 | g/T1 | Real Number | GainTempRatio | G/T = (Receiver Gain)/(System Temperature at the Receiver). The ratio of the receive antenna gain G to the total system temperature T is the "figure of merit" for the receiver (in dB/K). The figure of merit is independent of the point where it is calculated. However, the gain and system temperature must be specified at the same point. |
10 | C/No1 | C/No1 | Real Number | SpectralDensity | The carrier to noise density ratio (C/No) where C is the carrier power and No = kT (Boltzmann's constant x system temperature) is the noise density. It is equivalent to C/N with a normalized Bandwidth (B=1). |
11 | Bandwidth1 | Bandwidth1 | Real Number | Frequency | Bandwidth is the Receiver Bandwidth. |
12 | C/N1 | C/N1 | Real Number | Ratio | The carrier to noise ratio (C/N) where C is the carrier power and N = kTB (Boltzmann's constant x system temperature x bandwidth) is the noise power. |
13 | Eb/No1 | Eb/No1 | Real Number | Ratio | The energy per bit to noise ratio (Eb/No) where Eb is the energy per bit and No = kT (Boltzmann's constant * system temperature). |
14 | BER1 | BER1 | Real Number | Unitless | Bit Error Rate (BER) is the probability that a bit is in error (i.e. a zero is transmitted but a one is received). The BER is the number of bits in error divided by the total number of bits sent. STK uses table lookup from a .mod file to extract a BER given an Eb/No. STK interpolates the table as necessary to determine the appropriate bit error rate for a particular bit energy level. If the bit energy is smaller than the first value in the table, the bit error rate for the first value is used. If the bit energy is larger than the last value in the table, a default bit error rate of 1.0e-30 is used to indicate no errors. |
