Installation guide

Table 2 (at page 18). HVT is based on UMX APIs. Please make sure the RCB driver and the

HwTest driver are properly installed.

11.4.1 The Sine Wave Test

a) Start the test.

 Set up two Sora boxes. Place the two antennas about one meter apart.

 Select sine test on both boxes.

 Choose one box as the sender (select send) and the other as the receiver (select

receive).

 Click start button (b) at the sender. You will see the sender’s status bar (j) showing

“Sending 1MHz sine wave”. If a failure occurs, the error message will be shown in the

log window (k).

 Select a proper Tx gain (t) setting at the sender (for example 15dB).

 Choose the same sampling rate (r) as your RAB at the receiver.

 Click start button (b) at the receiver to capture the signal. You will see the waveform

displayed on two popup windows, as shown in the first row of Table 7. If failures occur,

the error messages will be shown in the log window (k).

 By default, the receiver gain is automatically adjusted (The AGC box (p) is checked). But

the user can disable the AGC and adjust the receiver gain manually by unchecking the

box.

 The user can also start a central frequency offset (CFO) calibration by clicking the auto

calibration button (e). The tool will automatically compute the frequency offset

between the sender and receiver and adjust the receiver’s frequency setting to match

the sender’s. The calibration result will be shown in the log window (k).

 The calibration results (parameters) can be stored in a file and the user can late

configure the RF front-end based on these values. Figure 41 shows a sample

configuration file.
