BT LE Signal Generator Command List
4. READ:GEN:SG:CH_NUM?
○
Description: Checks the setting of the BT_LE output channel
○
Response: 0 ~ 39
○
Default value: 0
5. READ:GEN:SG:FREQ?
○
Description: Checks the setting of the BT_LE output frequency[MHz]
○
Response: 2402.000 ~ 2480.000
○
Default value: 2402.000
6. CONF:GEN:SG:POWER <Range>
○
Description: Sets the BT_LE output power[dBm], Use to set power to be added to input signal of
DUT receiver under RF PHY Receiver Sensitivity test item and set as -70.0 [dBm] or according to a
user’s production specs.
○
Range: -5.0 ~ -70.0
○
Response : OK|ERR
○
Default value: -5.0
When test BT_LE Receiver Sensitivity, if DUT’s receiver sensitivity level is -93 dBm, MTP200B’s m
inimum output power is -70 dBm. Therefore, a user must connect 30dB Attenuator which prov
ided when MTP200B was released to RF Port to test.
Commands use example:
CONF:GEN:SG:PATH_LOSS 30
CONF:GEN:SG:POWER -93 // When the above commands are transmitted, -63dBm is outputte
d from RF port of MTP200B and -93dBm is inputted to input port of DUT passing through 30d
B Attenuator.
7. READ:GEN:SG:POWER?
○
Description: Checks the setting of the BT_LE output power[dBm]
○
Response: -5.0 ~ -70.0
○
Default value: -5.0
8. CONF:GEN:SG:BIT_PATTERN <Range>
○
Description: Sets the BT LE BIT pattern, Set as PRBS9 for F PHY Receiver Sensitivity test.
○
Range: ALL_ZEROS|ALL_ONES|10101010|11110000|PRBS9
○
Response: OK|ERR
○
Default value: ALL_ZEROS
